Question

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 following: 1. Expression for the inductor current for 0 < t < 10ms 2. Expression for the inductor current for 10ms < t < 30ms 3. Expression for the inductor current for 30ms < t < ∞ 4. 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 t=0).
