In the given circuit, switch S1 is in position A and switch S2 is open. Both switches are in these states for a very long time. At t=0, switch S1 moves from position A to B while switch S2 remains open. 10ms after switch S1 moves to position B, switch S2 is closed and remains closed for 20ms only. Determine the expressions for the inductor current for 0≤t<10ms, 10ms≤t<30ms, 30ms≤t<∞, and determine the time (in ms) after switch S1 moves to position B is the current in the inductor equivalent to 30% of the initial value (at ?=0).
