Problem 1: We begin by considering the circuit before time t=0, when it is in DC steady state with the switch open. The inductor can be replaced by a short circuit. So, for t < 0, the voltage acros
Solutions for Quiz #3 Problem 1: Because we have an AC voltage source and a DC current source, they are not at the same frequency and we have to solve this problem by superposition. Consider first the contribution from the DC current source. To zero
