Can you help me do b)?
In the circuit below, a) For t < 0, the switch has been open for a long time, find the inductor current? b) For t > 0, the switch is closed at t=0, find the inductor current using Thevenin's equivalent at the terminals a and b? And sketch the current waveform? c) Then find the steady-state, transient, forced and natural components? 22 V 10 v t=0 X 22 §
