EECS 215F07 Problem Set #2 Assigned: 9/19/07 Due: 9/26/07 Homework is due at the beginning of lecture. Reading Assignment: Alexander and Sadiku, Chapter 3,4 General Advice on Homework: 1. Start early. Don’t wait till Tuesday night. 2. Be sure to draw the circuit and label it properly with reference directions for currents and reference polarities for voltages. 3. Show all the important steps in your calculation. 4. Textbook problems are from the course textbook, “Fundamentals of Electric Circuits,” 3 rd Edition . The individual problem statements follow on the next pages. 1. . Find the equivalent resistances for the networks indicated but do not use Wye-Delta transforms as suggested by the text. Connect a test source and use nodal analysis. Chapter 2, Problem 53. Obtain the equivalent resistance R ab in each of the circuits of Fig. 2.117. In (b), all
