Problem Set for Midterm Exam on October 26, 2006 1. For the following circuit, solve for the current and voltages as shown below. Use all circuit analysis (i.e. 4) methods and check your work. Then, find the complex power, real/average power and reactive power delivered or absorbed by each element. Use these to check your work as well. Find V O and I O 2. For the circuits below, design the load, Z L such that maximum real/average power is transferred from the circuit network to the load. What is this maximum real/average power?
