# Homework
#9. First-Order Circuits

- Read Chapter 7 of Alexander & Sadiku's
*Fundamentals
of Circuit Analysis* (6th edition).

- Make sure you understand the answers to Review Questions 7.1
to 7.3,
and 7.5
to to 7.10 on pages 298 to 299. Review Question 7.4 is poorly worded, so don't worry about it. Also, note that several of these questions have five possible answers, the fifth of which should be labeled (e). Quiz
questions will be similar to these Review Questions or Review Questions from earlier
chapters.

- Turn in solutions to the following Problems on pages
299 to 310:
- All parts of Problems 7.1*, 7.3,
7.6, 7.11, 7.14, 7.24**, 7.27
- Part (a) of 7.39
- Part (a) of 7.40
- All parts of Problem 7.53 ***
- *The book's answer for part (a) of Problem 7.1 should also give
*R*'s value, which is 7 kΩ.
- **For each part of Problem 7.24, sketch the waveform as part
of your answer. Hint for this problem: use step functions for parts
(a), (b), and (d), and use ramp functions
for part (c).
- ***The book's answer for Problem 7.53 uses step functions,
but these are not necessary. For part (a) you could just write
5
*e*^{−t/2} A instead of 5*e*^{−t/2}*u*(*t*) A. For part (b) you could just write
6*e*^{−2t/3} A instead of 6*e*^{−2t/3}*u*(*t*) A.
