a) Find the inductor current in the circuit in Figure if v = −50 sin 250 t V, L = 20 mH, and i(0) = 10A.

b) Sketch v, i, p and w versus t. In making these sketches, use the format used in Figure. Plot over one complete cycle of the voltage waveform.

c) Describe the subintervals in the lime interval between 0 and 8π ms when power is being absorbed by the inductor. Repeat for the subinlervals when power is being delivered by the inductor.
