1. ECE 201 Circuit Theory I1 Sinusoidal response of circuits The switch is closed at t = 0. Determine the current i(t) for t >= 0. i(t)

2. ECE 201 Circuit Theory I2 Write KVL around the loop i(t)

3. ECE 201 Circuit Theory I3 The complete solution

4. ECE 201 Circuit Theory I4 “Transient” solution “Steady-State” solution (This is what we study now)

5. ECE 201 Circuit Theory I5 Steady-state solution Sinusoidal The frequency is the same as the frequency of the input signal Maximum amplitude is different from that of the source Phase angle differs from that of the source

6. ECE 201 Circuit Theory I6 Solve for these
