UNIVERSITY OF CALIFORNIA College of Engineering Department of Electrical Engineering and Computer Sciences B. E. BOSER EE 42 / 100 Spring 2008 Problem Set 2 Due Wednesday, February 6, 2008 1. (a) Find expressions for the power P 1 dissipated by source V 1 and the power P 2 dissipated by source I 2 as a function of V 1 and I 2 . (b) Calculate P 1 and P 2 for V 1 = 10 V and I 2 = 1 A and verify that the total power dissipated by the circuit is zero. (c) Repeat ( 1b ) for V 1 = 10 V and I 2 = 1 A. (d) Repeat ( 1b ) for V 1 = 10 V and I 2 = 1 A. (e) Repeat ( 1b ) for V 1 = 10 V and I 2 = 1 A. 2. (a) For the circuit shown below ﬁnd expressions for the current i 1 and the power P 1 dissipated in resistor R 1 as a function of V 1 and the resistance R 1 . (b) Calculate the values of i 1 and P 1 for V 1 = 5 V and R 1 = 1 k Ω . (c) Repeat ( 2b ) for V 1 = 5 V and R 1 = 1 k Ω . 3. The circuit shown below is used to measure the voltage/current relationship for a practical bat-
