Homework 19 ECE201: Linear Circuit Analysis Due in class: Wednesday, October 12, 2011 1. The configuration of an RC circuit is given below. a. Find the effective resistance seen by the capacitor. b. Determine the time constant of the RC circuit. c. If V ( t ) = 10 u ( t ) and V C (0) = 0V, plot V C ( t ) for 0 < t < 2 seconds. d. If V ( t ) = 10 u ( t ) and V C (0) = 4V, plot V C ( t ) for 0 < t < 2 seconds. e. If V ( t ) = 10 u ( t ) and V C (0) = –2V, plot i C ( t ) for 0 < t < 2 seconds.

Unformatted text preview: L = 2H. The initial voltage across each inductor at t = 0 is zero. a. Find the time constant 1 of the circuit when the switch is open. b. Find the time constant 2 of the circuit when the switch is closed. c. If i (0) = 2A and t = 1 , plot V out ( t ) for 0 < t < 1 . d. If i (0) = 2A and t = 1 , plot V out ( t ) for 0 < t < 1 + 2 . e. If i (0) = 2A and the switch closes at t = 1 , but opens again at t = 2 , then what is the voltage V L across the 3 L inductor at time t = 2 1 + 2 ....
