Question:

In Fig. 30.11, suppose that ε = 60.0 V, R = 240 Ω and L = 0.160 H. Initially there is no current in the circuit. Switch S2 is left open, and switch S1 is closed.
(a) Just after S1 is closed, what are the potential differences vab and Vbc?
(b) A long time (many time constants) after S, is closed, what are vab and vbc?
(c) What are vab and Vbc at an intermediate time when i = 0.150A?
