| 14 If you need professional help with completing any kind of homework, Online Essay Help is the right place to get it. Explain why or why not. The income distribution of a certain country is given by f(x)=\frac{19}{20}x^2+\frac{1}{20}x a) Sketch the Lorenz curve for this function b) Compute f(0,60) and interpret your answer c) Compute the c, Describe the shift in either the AD or AS (aggregate demand OR aggregate supply) curves, and in what range of the AS (if relevant), that would produce the following outcomes for the economy. (120 V ∠ 0o) - (120 V ∠ 120o) = 208 V ∠ -30o, (120 V ∠ 120o) - (120 V ∠ 0o) = 208 V ∠ 150o. This leads to a rightward shift of the short run Phillips Curve. I recommend resistor values between 1 kΩ and 100 kΩ. You may find it necessary to discuss this circuit in detail with your students before they are ready to troubleshoot it. Another time-saving technique is to re-use the same components in a variety of different circuit configurations. The Phillips Curve illustrates the relationship between the rate of inflation and the unemployment rate. In other words, when unemployment was high, inflation was low; and when unemployment was low, inflation rose rapidly. Follow-up question: what must be done to make the two alternators’ frequencies equal to each other? If your students will be working with real circuits, then they should learn on real circuits whenever possible. Follow-up question: what type and size of component will provide this exact amount of impedance at 600 Hz? Mathematically analyze the circuit, solving for all voltage and current values. Bob's workers may expect more inflation as well and negotiate their wages even higher. When we are accounting for the phase shift of a voltage drop in our answer, does the “polarity” of the voltage drop matter? A rec, Assume expected inflation rises. Because of this connection, whatever events lead to a shift in aggregate supply will also lead to a shift in the short run Phillips Curve, whether they are positive or negative. Finally, the mayor of Ceelo passes a law increasing the minimum wage. The Phillips Curve illustrates the relationship between the rate of inflation and the unemployment rate. No government policy, including changes in the money supply growth rate, can change the natural rate of unemployment. © copyright 2003-2021 Study.com. Economists call this the Phillips Curve. The “phase-locking” phenomenon of two paralleled alternators is very important for students to understand if they are to do any work related to AC power generation systems. You should know that the line voltage of a three-phase, Y-connected, balanced system is always greater than the phase voltage by a factor of √3. Ask your students to explain what effect would leakage inductance have on the load impedance of this circuit. Yes, it is out of character for me to show two pages of solution in the “answer” section of one of my questions! A note to those instructors who may complain about the “wasted” time required to have students build real circuits instead of just mathematically analyzing theoretical circuits: What is the purpose of students taking your course? Ask them to explain why one of these parameters is affected but the other is not. For example, the impedance of a series-connected resistor (R) and inductor (L) would be represented as follows, with angular velocity (ω) being equal to 2 πf: Using the same algebraic notation, represent each of the following complex quantities: One possible point of confusion here is the sign of j after inversion. and career path that can help you find the school that's right for you. Get your assignment help services from professionals. B. Discuss these issues with your students in the same Socratic manner you would normally discuss the worksheet questions, rather than simply telling them what they should and should not do. An open failure of the fixed resistor in the upper-left arm of the bridge could cause this to happen: Complex quantities may be expressed in either rectangular or polar form. Create an account to start this course today. Observing this trend, Bob may expect inflation to go up by 5% next year, and raise prices by this amount. Challenge question: once the breaker is closed, can the two alternators ever fall out of phase with each other again? Who We Are. Which of these mathematical forms (rectangular or polar) relates more naturally to measurements of voltage or current, taken with meters or other electrical instruments? Ask your students why polarity markings need to be provided in DC electrical networks, as an essential part of the voltage figures. Let's visit the town of Ceelo to find out what factors will lead to a shift in the Phillips Curve. One way you can save time and reduce the possibility of error is to begin with a very simple circuit and incrementally add components to increase its complexity after each analysis, rather than building a whole new circuit for each practice problem. If listened to with an audio detector, you may even hear the change in timbre while moving the wiper from one extreme to the other. As a member, you'll also get unlimited access to over 83,000 lessons in math, English, science, history, and more. flashcard sets, {{courseNav.course.topics.length}} chapters | The answers given for this question should clarify that point. The only bad part about this is that doing complex-number arithmetic by hand can be very tedious. Increases in aggregate supply like these will shift the short run Phillips Curve to the left so that less inflation is seen at each unemployment rate. The greatest problem with closing the breaker is the 37o phase shift between the two alternators’ output voltages. A broken connection between the right-hand terminal of the potentiometer and the bridge could cause this to happen: It is essential, of course, that students understand the operational principle of this circuit before they may even attempt to diagnose possible faults. Challenge question: what practical function does this circuit perform? Switch left: Θ = -45o (Vout lagging behind the source voltage), Switch right: Θ = 45o (Vout leading ahead of the source voltage). While rectangular notation is mathematically useful, it does not apply directly to measurements taken with real instruments. In this lesson, we're talking about the factors that lead to a shift in the Phillips Curve. So long as complex quantities are used, AC bridge circuits “balance” just the same way that DC bridge circuits balance. This negative supply shock causes a rightward shift of the short run Phillips Curve. When this happens, Bob is forced to pay low-wage workers a higher wage, so his profit potential goes down and he decides to let go of a few smaller lawn customers and let go of five workers. A. A remote speaker for an audio system is connected to the amplifier by means of a long, 2-conductor cable: This system may be schematically modeled as an AC voltage source connected to a load resistor: Suppose we decided to use the 2-conductor cable for more than just conveying an audio (AC) signal - we want to use it to carry DC power as well to energize a small lamp. B) The curve will not be affected. This phase-shifting bridge circuit is supposed to provide an output voltage with a variable phase shift from -45 o (lagging) to 45 o (leading), depending on the position of the potentiometer wiper: Suppose, though, that the output signal is stuck at -45 o lagging the source voltage, no matter where the potentiometer is set. Without the polarity marks as “frames of reference” for the phase angles, it is impossible to determine the resultant line voltage from the two 120 VAC phase voltages. The simplest circuit, of course, is a single component connected to a power source! Cheap essay writing sercice. In most sciences, realistic experiments are much more difficult and expensive to set up than electrical circuits. Follow-up question: identify the effects of various component failures in this circuit. This question is really a series of practice problems in complex number arithmetic, the purpose being to give you lots of practice using the complex number facilities of your calculator (or to give you a lot of practice doing trigonometry calculations, if your calculator does not have the ability to manipulate complex numbers!). As each source is considered separately, the reactive components ensure each load receives the correct source voltage, with no interference. credit-by-exam regardless of age or education level. Polar form relates much better to the voltmeter’s display of 5 volts. Take A Sneak Peak At The Movies Coming Out This Week (8/12) “Look for the helpers” – Celebrities helping out amid Texas storm; New Movie Releases This Weekend: February 19th – February 21st The output voltage at the full-right wiper position will be mostly unaffected. Plus, get practice tests, quizzes, and personalized coaching to help you succeed. Explain your answer. My [pets are safe. Sociology 110: Cultural Studies & Diversity in the U.S. Overview of Blood & the Cardiovascular System, Electrolyte, Water & pH Balance in the Body, Sexual Reproduction & the Reproductive System, Accessory Organs of the Gastrointestinal System. imaginable degree, area of If one or more of your students find out how to do so through their research, don’t consider it “cheating.” Rather, applaud their research, because they found a quicker path to a solution. Do they make any sense at all, given the fact that AC by its very nature has no fixed polarity (because polarity alternates over time)? In this case, consumers and businesses in the town would probably expect prices to go up by 3% this year. Discrete Semiconductor Devices and Circuits. So, I suggest the following alternative approach: students should build their own “practice problems” with real components, and try to mathematically predict the various voltage and current values. Students don’t just need mathematical practice. However, in this case I believe there is still much to be learned from examining a proof like this shown step-by-step. For successful circuit-building exercises, follow these steps: For AC circuits where inductive and capacitive reactances (impedances) are a significant element in the calculations, I recommend high quality (high-Q) inductors and capacitors, and powering your circuit with low frequency voltage (power-line frequency works well) to minimize parasitic effects. Furthermore, having students build their own practice problems teaches them how to perform primary research, thus empowering them to continue their electrical/electronics education autonomously. Some students might suggest that the 3.000 volt reading and the 4.000 volt reading on the other two voltmeters represent the rectangular components (real and imaginary, respectively) of voltage, but this is a special case. While this approach makes students proficient in circuit theory, it fails to fully educate them. a practical inductor with winding resistance), the voltage magnitude will be neither the real nor the imaginary component, but rather the polar magnitude. There is actually a way to solve for the values of Lx and Rx in a Maxwell-Wien bridge circuit without using complex numbers at all. Now, suppose that instead of 3%, inflation was actually 4% this year. You may build one using 1 μF capacitors and 2.7 kΩ resistors that will successfully operate on 60 Hz power-line excitation. As usual, avoid very high and very low resistor values, to avoid measurement errors caused by meter “loading”. Assume that the capacitors are of such large value that they present negligible impedance to the audio signal (ZC ≈ 0 Ω) and that the inductors are sufficiently large that they present infinite impedance to the audio signal (ZL ≈ ∞). Discuss with your students how the Maxwell-Wien bridge would be a suitable topology for use with a noise source, whereas other bridge topologies might not. I never cease to be amazed at how poorly students grasp instructions when presented in a typical lecture (instructor monologue) format! The simplest “null detector” for this type of AC bridge would be a sensitive pair of audio headphones, as 600 Hz is well within the audio range, and would be heard as a tone in the headphones. Phillips released a study of wages in the United Kingdom, he found that there was an inverse relationship between inflation and unemployment. The following table shows selected data on unemployment and inflation in the United States between 1974 and 1978. But most of us plan for our students to do something in the real world with the education we give them. 16 chapters | An error occurred trying to load this video. Bob's profit potential goes down, and without being able to raise prices, he's forced to lay off some workers. Determine the phase shift of the output voltage (Vout) with reference to the source voltage (0o) for each of the two switch positions, assuming the source frequency is such that XC = R: Note: you should be able to do all the necessary math mentally, without the aid of a calculating device! [Father 3. Consequently, this is really nothing new for your students if they’ve already studied DC Wheatstone bridge circuits. Decreases in aggregate supply like these shift the short run Phillips Curve to the right so that more inflation is seen at each unemployment rate. Services. Sciences, Culinary Arts and Personal Question 5: List some of the sensitivity tools of Excel. This means that Bob would set his prices 3% higher, and Bob's workers would expect a cost-of-living adjustment in their wages of 3%. Show that these solutions (Z2 = Rp Rs and Z2 = Xp Xs) hold true for resistor-capacitor series and parallel equivalent networks as well. It works best when the excitation frequency is such that XC = R in each arm of the bridge: Supposing that XC does equal R in each arm of the bridge, and that the potentiometer resistance is sufficiently high to limit current through it to a negligible level (in other words, Rpot >> R). flashcard set{{course.flashcardSetCoun > 1 ? Spend a few moments of time with your class to review some of the “rules” for building circuits before they begin. If it is not evident from the answers, 1/j is equal to −j, so that the impedance of an inductor (j ωL) becomes −j [1/(ωL)] when converted into an admittance. An AC bridge circuit commonly used to make precision measurements of inductors is the Maxwell-Wien bridge. A brief proof is given here: Otherwise, the admittance equation \((Y_s=\frac{1}{R_s}+jwC_s)\) will not make sense. Remind them that “1” is a real quantity, possessing an (implied) imaginary component of 0, and that it could very well have been written as 1 j0. Not sure what college you want to attend yet? Don't have an AAC account? Of course, complex numbers may also be used to calculate VAB, but the phasor approach has the benefit of graphical intuitiveness. That is, its resistance value is precisely equal to what the “digit” and “multiplier” color bands declare. I suggest you let your students discover how to use the complex number facilities of their scientific calculators on their own. A broken connection between the left-hand terminal of the potentiometer and the bridge could cause this to happen: Suppose, though, that the output signal registers as it should with the potentiometer wiper fully to the right, but diminishes greatly in amplitude as the wiper is moved to the left, until there is practically zero output voltage at the full-left position. You may find it necessary to discuss this circuit in detail with your students before they are ready to troubleshoot it. Answers may vary. In 1958, when A.W.H. Let the electrons themselves give you the answers to your own “practice problems”! My experience has been that students both young and old take to this challenge readily, because they realize learning how to use their calculators will save them a tremendous amount of hand calculations! Exploit the convenience inherent to your science, and get those students of yours practicing their math on lots of real circuits! 's' : ''}}. However, one of these forms relates better to real-world measurements than the other. Such “power-plus-data” strategies are made possible by the Superposition Theorem and the linearity of resistors, capacitors, and inductors. $$\frac {1}{\frac{1}{15\angle45^0}+\frac{1}{92\angle-25^0}}=$$, $$\frac {1}{\frac{1}{1200\angle73^0}+\frac{1}{574\angle21^0}}=$$, $$\frac {1}{\frac{1}{23k\angle-67^0}+\frac{1}{10k\angle-81^0}}=$$, $$\frac {1}{\frac{1}{100\angle-34^0}+\frac{1}{80\angle19^0}+\frac{1}{70\angle10}}=$$, $$\frac {1}{\frac{1}{89k\angle-5^0}+\frac{1}{15k\angle33^0}+\frac{1}{9.35k\angle45}}=$$, $$\frac {1}{\frac{1}{512\angle-34^0}+\frac{1}{1k\angle-25^0}+\frac{1}{942\angle-20}+\frac{1}{2.2k\angle44^0}}=$$, $$\frac {1}{(15\angle60^0)}=0.667 \angle-60^0$$, $$\frac {1}{(750\angle-38^0)}=0.00133 \angle38^0$$, $$\frac {1}{\frac{1}{15\angle45^0}+\frac{1}{92\angle-25^0}}=14.06 \angle36.74^0$$, $$\frac {1}{\frac{1}{1200\angle73^0}+\frac{1}{574\angle21^0}}=425.7 \angle37.23^0$$, $$\frac {1}{\frac{1}{23k\angle-67^0}+\frac{1}{10k\angle-81^0}}=7.013k \angle-76.77^0$$, $$\frac {1}{\frac{1}{100\angle-34^0}+\frac{1}{80\angle19^0}+\frac{1}{70\angle10}}=29.89 \angle2.513^0$$, $$\frac {1}{\frac{1}{89k\angle-5^0}+\frac{1}{15k\angle33^0}+\frac{1}{9.35k\angle45}}=5.531k \angle37.86^0$$, $$\frac {1}{\frac{1}{512\angle-34^0}+\frac{1}{1k\angle-25^0}+\frac{1}{942\angle-20}+\frac{1}{2.2k\angle44^0}}=256.4 \angle9.181^0$$. Another reason for following this method of practice is to teach students scientific method: the process of testing a hypothesis (in this case, mathematical predictions) by performing a real experiment. The venerable X10 network system is an example for residential power wiring, while power distribution utilities have been using this “PLC” technology (the acronym not to be confused with Programmable Logic Controllers) for decades over high-voltage transmission lines. In cases where resistance and reactance are mixed (e.g. Typically, students practice by working through lots of sample problems and checking their answers against those provided by the textbook or the instructor. Anyone can earn Using inductors and capacitors as “filtering” components, though, we can make this system work: Apply the Superposition Theorem to this circuit to demonstrate that the audio and DC signals will not interfere with each other as they would if directly connected. Challenge question: combine the result of that simplification with the equations solving for scalar impedance of series and parallel networks (\(Z^2_s= R^2_s+X^2_s\) for series and \(Z^2_p= \frac{1}{\frac{1}{R^2_p}+\frac{1}{X^2_p}}\) for parallel) to prove the following transformative equations, highly useful for “translating” a series network into a parallel network and visa-versa: Due to the complexity of the algebra, I will show the complete solution here: In answer to the challenge question, where we now introduce scalar relationships for series and parallel networks: Follow-up question: the original equivalent networks were comprised of a resistor (R) and an inductor (L). What does the flattening of the curve imply, at a macroeconomic level? Carefully build this circuit on a breadboard or other convenient medium. If your goal is to educate theoretical physicists, then stick with abstract analysis, by all means! A note on reactive components: use high-quality capacitors and inductors, and try to use low frequencies for the power supply. If the source frequency is 400 Hz, and the two fixed-value resistors are 1 kΩ each, calculate the inductance (Lx) and resistance (Rx) of the inductor being tested. Follow-up question: identify another possible component failure that would exhibit the same symptoms. If excited by a “clean” sine-wave, however, no change in timbre should be heard because there are no harmonics present. The benefit of students researching other means of solution simply provides more alternative solution strategies to the same problem, which is a very good thing. Explain why this bridge circuit can never achieve balance: Even though impedance magnitudes may be balanced, the phase angles cannot. TEFL, Integrated Learning … Suppose that an economy has the Phillips curve TT = TT-1 - 0.5(u - 5). No matter what kind of academic paper you need, it is simple and affordable to place your order with My Essay Gram. Get the unbiased info you need to find the right school. What is the natural rate of unemployment? All rights reserved. Suppose we have two equivalent LR networks, one series and one parallel, such that they have the exact same total impedance (Ztotal): We may write an equation for the impedance of each network in rectangular form, like this: Since we are told these two networks are equivalent to one another, with equal impedances, these two expressions in rectangular form must also be equal to each other: Algebraically reduce this equation to its simplest form, showing how Rs, Rp, Xs, and Xp relate. Ask your students to calculate how fast the voltages from these two alternators “roll” in and out of phase with each other. They also need real, hands-on practice building circuits and using test equipment. Question 4: List five business applications for which one can use excel. However, if we were to simply connect the DC power source in parallel with the amplifier output at one end, and the lamp in parallel with the speaker at the other, bad things would happen: If we were to connect the components together as shown above, the DC power source will likely damage the amplifier by being directly connected to it, the speaker will definitely be damaged by the application of significant DC voltage to its coil, and the light bulb will waste audio power by acting as a second (non-audible) load. You may wish to ask your students to explain the rationale behind each step, especially in the first part where we deal with real and imaginary terms. C) There will be a shift, Working Scholars® Bringing Tuition-Free College to the Community, An increase in the price of oil from abroad, A negative supply shock, such as damage from a hurricane, Improvements in technology across the economy, A decrease in the price of oil from abroad, A positive supply shock, for example, when aggregate supply goes up because, Define the Phillips Curve and give examples of factors that shift it to the left and to the right, Understand why inflation and unemployment are related to aggregate supply. For instance, which form of AC voltage expression, polar or rectangular, best correlates to the total voltage measurement in the following circuit? 3 SECOND EDITION:Skills for Success SPECIAL EDITION READING AND WRITING Teacher’s Handbook 1 CONTENTS Teaching with Q: Skills for Success, Second Edition On a Journey to Think Critically Colin S. Ward, Reading and Writing Level 3 Author Using Q Video in the Classroom Alison Rice, Video Consultant To Go Online or Not to Go Online Chantal Hemmi, Ed.D. credit by exam that is accepted by over 1,500 colleges and universities. To learn more, visit our Earning Credit Page. When the price of oil from abroad declines, the short run Phillips Curve shifts to the left. Note that neither of the two equations solving for unknown quantities \((R_x = \frac{R^2}{R_s} \ \ \ and \ \ \ L_x=R^2C_s)\) contain the variable ω. - Definition & Examples, Anoxic Environment: Definition & Conditions, Tech and Engineering - Questions & Answers, Health and Medicine - Questions & Answers, Suppose that the natural real GDP is constant. Follow-up question: explain why it would not work to use an oscilloscope as the “detector” in this bridge circuit: Challenge question: explain how you could use this same oscilloscope as the detector in this bridge circuit without changing the ground location at the lower terminal of the AC source. Can TI’s New DC-DC Converter Really Extend Battery by 50 Percent? For example, when inflation expectations go down, the short run Phillips Curve shifts to the left. Mathematically, it does not matter which form of expression you use in your calculations. Inflation and unemployment are closely related to aggregate supply, because it takes workers to produce the supply of goods, and wages tend to be one of the largest expenses for businesses. How Long is the School Day in Homeschool Programs? Because of this connection, whatever events lead to a shift in aggregate supply will also lead to a shift in the short run Phillips Curve.

Inflation and unemployment are inversely related. Published under the terms and conditions of the Creative Commons Attribution License. As unfortunate as it sounds, if a hurricane passes through the town of Ceelo, Bob's office sustains major damage that shuts his business down. How does globalization affect the Phillips curve? Explain why. Then, pose the scenario of a real transformer, complete with leakage inductance. Factors That Lead to the Phillips Curve. Academia.edu is a platform for academics to share research papers. Draw the schematic diagram for the circuit to be analyzed. Inflation and unemployment are closely related to aggregate supply, because it takes workers to produce the supply of goods and wages tend to be one of the largest expenses for businesses. It has been my experience that students require much practice with circuit analysis to become proficient. If there are any substantial errors (greater than a few percent), carefully check your circuit’s construction against the diagram, then carefully re-calculate the values and re-measure. ALL YOUR PAPER NEEDS COVERED 24/7. An interesting thing to note about using line power is that any distortions in the excitation sine-wave will become obvious when the potentiometer wiper is turned toward the differentiating position (where Θ is positive). Alright, time to review. Jon has taught Economics and Finance and has an MBA in Finance. It is the policy of the Ambulatory Surgery Center Association (ASCA) to ensure that all individuals who have the ability to control or influence the content of an educational activity disclose all financial relationships with any entity whose products or services are … Finally, suppose that Bob's son, Bobby Jr., wins the science fair at school, inventing a superfreak machine that makes everyone twice as productive whenever they listen to disco music.
