ELEC 225, Fall 2009
Prof. Rich Kozick

Homework 2


Date Assigned: Wednesday, September 2, 2009
Date Due: Wednesday, September 9, 2009

  1. Reading: In the Nilsson/Riedel text, please continue to study Chapter 2, and read Chapter 3 carefully and completely. Begin reading Chapter 4, Sections 4.1-4.4, on the node-voltage method for the week of September 7.

  2. We will have Lab 1 on Thursday, Sept. 3 in Dana 305. Please be ready to begin lab at 8:15 AM.

  3. Office hours (other times can be arranged - talk to me in class, send email, or call): 
    Monday      2-3  PM
Tuesday     10 AM - 11 AM  & 1-2 PM (unless noted)
Thursday    11 AM - 12 PM
Friday      9-10 AM

  4. Please check your exam / project schedule and compare with the tentative exam dates on the syllabus. We will finalize the exam dates for this course by Monday, Sept. 7.

  5. Please solve the following problems, and submit solutions in class on September 9:
    Chapter 2: Problems 2.22, 2.23, 2.28(a), 2.29, and 2.30.
    Chapter 3: Problems 3.7, 3.8, and 3.10.

    Note that with clever analysis, these problems can be solved without solving a system of simultaneous linear equations. You should try to study each circuit to obtain such a solution.

  6. Please solve problem 3.10 using PSpice and submit a printout of your PSpice circuit (showing the power dissipated by the 30 ohm resistor) on Sept. 9. The PSpice tutorials from Lab 1 may be helpful (the third link is new):

  7. Extra Credit: (Please submit before Sept. 16)
    Use PSpice to solve Problem 2.31 in the text and find the current i_delta, the voltage v_o, and the power of each element in the circuit. Recall that we analyzed this problem in class on Sept. 2 and this was listed as the "Challenge" in Lab 1.
Thank you.
