2. The circuit in Fig. 2 represents an energy storage bank with vi(0)=-3 V, v2(0) = 5 V, v3(0)=-5 V.
(a) If the switch Si is closed at tı > 0, find the values of vi, v2, and v3 after ti.
(b) Following (a), if the switch S2 is closed at 12 >ti. Find the final values of vi, vz, and va after 12.
3. Let iz(0) = 0. Find the current il(t) of the circuit shown in Fig. 3 for t> 0.
