Homework 12 Due: Wednesday, September 21 1 Find the Thevenin and Norton equivalent circuits seen at the terminals A-B for the circuit depicted in Figure 1. 40 40 10 Friday, September 16, 2011 Figure 1: Model circuit for Problem 1. 2 In the circuit of Figure 2, R1 = 1 kΩ, R2 = 4 kΩ, RL = 3 kΩ, vs1 = 30V, i2 = 19 mA and i3 = 5 mA. Find the Thevenin and Norton equivalents of the circuit in the dashed box. Then find iL and the power absorbed by RL. 3 (a) Find the Thevenin equivalents for the circuit of Figure 3 in terms of the literals vs1 and is2. 1 Friday, September 16, 2011 Figure 2: Model circuit for Problem 2. (b) If the A-B is terminated by a 30 kΩ load, and vs1 = 60 V, and is2 = 10 mA, find the power delivered to the load. 12 12 12 8 4 Friday, September 16, 2011 Figure 3: Model circuit for Problem 3. 2
