Date Assigned: Thursday, February 18, 2010 Date Due: Thursday, February 25, 2010
Reading:
In the Nilsson/Riedel text, please continue to study Chapter 10
for the week of Feb. 22.
You may also find it interesting to read Chapter 11 on three-phase
circuits.
We will not discuss much (if any) of Chapter 11 in class, but
EE majors will study this topic in a senior course, ELEC 491.
Please solve the following problems in Chapter 10
and submit solutions in class on Feb. 25:
Problems 10.4 and 10.6:
For these problems, find the relevant voltage and current phasors,
then apply equations (10.2), (10.3), and (10.10) to compute the
average power, P.
Problem 10.13.
Explain the steps that you used to estimate the resistance and
inductance values for the transformer in
Lab 3.
That is, show how you used measured data to estimate
R1, R2,
L1, L2, and M.
Also, briefly summarize how closely your transformer in lab
is approximated as an ideal transformer.
Please submit your explanation in class on Feb. 25.
We will continue to work with transformers in
Lab 3 on Thursday, February 18.
All students will attend lab on Feb. 18,
and please bring your breadboards and results from
Lab 2.
We will have a short quiz on the topic of ideal transformers
in class on Tuesday, Feb. 23.
The quiz will use the "step-up" and "step-down" transformer model
that we discussed in class on Feb. 18.
Exam 1 will be on Tuesday, March 2.
See Homework 6 for details about the topics
for the exam.
I will try to get back to homework being due on Tuesdays after the exam.
