Pre-Lab Information

Rectifiers are widely used in power supplies to provide the required dc voltage.

Materials and equipment Needed:

Materials:

• One 240/24 Vrms center-tapped transformer
• Two diodes 1N4001
• Two 2.2 kΩ resistors
• One 100 μF, 50 V electrolytic capacitor (any voltage rating is fine since is simulation only)
• One fuse (any rating is fine since is simulation only)

Equipment:

• Oscilloscope
• Function generator

Procedure:

In this experiment, use Multisim to connect a low-voltage (24 V ac) transformer to a 240V 50Hz ac line (use the function generator for simulation and consider whether the typical specification is peak or rms). Connect the half-wave rectifier shown in Figure 1. Notice the polarity of the diode. Be sure to set the tolerance of the resistor to 5%. Connect the oscilloscope so that channel 1 is across the transformer and channel 2 is across the load resistor. View the secondary voltage, V_SEC, and the load voltage, V_LOAD, for this circuit and observe their waveforms.

8. Measure the rms input voltage V_SEC to the diode (remember to convert the oscilloscope reading of V_SEC to rms) and the output peak voltage, V_LOAD. Tabulate all data gathered. Capture screenshots of your measurements.

Figure 1

• The output isn’t very useful as a dc source because of the variations in the output waveform. Connect a 100 μF capacitor (C₁) with a tolerance of 10% in parallel with the load resistor (R_L). (note the polarity of the capacitor). Measure the dc load voltage, V_LOAD, and the peak-to-peak ripple voltage, V_RIPPLE, in the output. Measure the ripple frequency. Capture screenshots. Tabulate all data gathered and compare the results with and without the filter capacitor.

3. Disconnect the power and change the circuit to the full-wave rectifier circuit shown in Figure 2. Notice that the ground for the circuit has changed. The oscillopscope ground needs to be connected as shown. Check your circuit carefully before applying power. Compute the expected peak output voltage. Then apply power and view the V_SEC and V_LOAD waveforms.

Measure the V_SEC rms and peak output voltage V_LOAD without a filter capacitor. Capture screenshots of the waveforms.

Tabulate all data gathered.

Figure 2

4. Connect the 100 μF capacitor in parallel with the load resistor. Measure V_LOAD, the peak-to-peak ripple voltage, and the ripple frequency as before. Capture screenshots. Tabulate all gathered data and compare the results with and without the filter capacitor.
5. Investigate the effect of the load resistor on the ripple voltage by connecting a second 2.2 kΩ, 5% tolerance, load resistor in parallel with R_L and C₁ in the full-wave circuit of Figure 3. Measure the ripple voltage. Captures a screenshot.
6. Conclusion: Write a detailed conclusion about this lab experiment. The conclusions should explain in detail and in words why the results were different at different stages in the lab and what the implications are of the different results. You should make sure that you include the following:
7. the effect of capacitor on the output voltage
8. and the effect of additional load on the ripple voltage

Please note, however, that addressing only a and b will not result in full points.

7. Evaluation and Review Question:

What advantage does a full-wave rectifier circuit have over a half-wave rectifier circuit?

Write your lab report as a professional document. Make sure your tables presenting data are clear with units and headings. Save the document as Lab2YourGID.docx (ex: Lab2G00050331.docx), or in another relevant document format.

Problem Set 7

⦁ Between 1995 and 1997, American Airlines competed with several low-cost-carriers on routes from Dallas/Fort Worth. The US Department of Justice sued alleging predatory pricing. A judge disagreed. Read this article from the Wall Street Journal (available through the Hunt Library ProQuest database):

Wilke, J. R., & McCartney, S. (2001, April 30). American Airlines secures antitrust win — Judge dismisses U.S. case, says competitive moves were company’s right. Wall Street Journal (Eastern edition), pp. A.3.

The antitrust legal standard for predatory pricing is pricing below variable or marginal cost. Discuss why the plaintiffs lost this case in the face of what most lay people would consider predatory pricing. Hint: Consider how to compute marginal cost for an airline.

⦁ Most large airlines operate networks, or hub-and-spoke systems, which connect many spoke cities (or nodes) with flights to and from a hub airport.
⦁ A network carrier serves 39 spoke cities from a single hub. How many city-pairs does it serve? (A city-pair is City A to City B. City A to City B and City B to City A are consider just one city-pair)
⦁ This same airline adds a 40th spoke city to its network using a 100 seat capacity aircraft. On a flight from this 40th spoke to the hub, how many passengers, on average, does it need to attract to each destination to achieve an 80% load factor?
⦁ How can a network airline profitably serve smaller cities than a low-cost-airline? (Hint: Consider 2b above).
⦁ A network carrier serves some small cities close to its hub with regional jets which have much higher seat-mile-costs (CASM) than larger mainline jets. The average fare from these cities to the hub does not cover fully allocated costs. Is this rationale?
⦁ Networks are subject to negative externalities. How might such externalities affect a network carrier’s decision to add another spoke city to its network? Explain. (You may wish to use marginal benefit/cost analysis).

⦁ In the early 1990s, Airbus and Boeing were both considering building a new Very Large Aircraft (VLA). Airbus faced this decision tree. Boeing’s decision was similar. Why did only Airbus build the VLA, the A-380? The numbers in parentheses indicate the 20 years incremental profit in billions of dollars for Airbus and Boeing.

To the shareholders of Tamarak Corporation,

We have audited the accompanying balance sheet of Tamarak Corporation as of October 31, 2009, and the related statements of income, retained earnings, and cash flows for the past year. These financial statements are the responsibility of the company’s management. Our responsibility is to express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

The company has included in property and debt in the accompanying balance sheet certain lease obligations that, in our opinion, should be expensed in order to conform with generally accepted accounting principles. If these lease obligations were capitalized, property would be decreased by $4,000,000, long-term debt by $2,000,000, and retained earnings by $180,000 as of October 31, 2009, and net income and earnings per share would be decreased by $180,000 and $0.62, respectively, for the past year.

Required: Complete the above qualified audit report by preparing the opinion paragraph. Do not date or sign the report.

Part Two:

1. A clinical psychologist would like to determine whether there is a relationship between observer ratings of children’s avoidant behaviors and scores on an established diagnostic interview assessing childhood anxiety disorders. He administers the diagnostic interview to 28 children and records these scores. He then trains an observer to independently rate carefully-defined avoidant behaviors for each of the 28 children. These scores are totaled for an overall “avoidant behavior index.” On both the interview and the behavioral ratings, a higher score indicates higher levels of behaviors/symptoms. These scores are listed in the table below. Conduct a Pearson correlation coefficient analysis to determine whether there is a relationship between the interview scores and behavioral ratings for this group of children.

The steps will be the same as the ones you have been practicing in Part One of the assignment—the only difference is that you are now responsible for creating the data file as well. Remember to name and define your variables under the “Variable View,” then return to the “Data View” to enter the data.
