Question
Q 1. Consider the circuit below. For t<s, the switch is in position 1 and you may assume the system has reached steady state. The source is is an AC source with w = 2 rad/s. Its phasor diagram is shown on the left. The switch moves from position 1 to position 2 at t =s 2 and remains in position 2. (a) Find the current ia (E s). (i.e., just before the switch ia S moves). (b) Find the current ia(2n s). ia (2π s) 1 2 H Im 2 ia is (1 4 V Re |Is| = 6 A Is
