Question

- Switch S Switch S2 42 х. 42 t 0 t-0 100u(t 1F + 4H 20) 40) LOOP 2 LOOP1 Figure 1 0. Before switch St closes, no energy is Switch S2 stays open while switch St closes at t stored in the inductor or capacitor. Namely-i (0- ) = uc ( 0) = 0. (a.) (10 points) Find i(t) when switch S, closes but switch S2 stays open. (b.) (10 points) After a long time or after an appropriate amount of time where the measured current in loop 1 of Figure 1 reaches steady state, switch S1 opens and switch S2 closes. Find i2(t) for t > 0. (c.) (10 points) Find the voltage across the capacitor, vc (t) for t > 0 while switch S2 remains closed and switch Si remains open.
