Consider the circuit shown in Fig. P30.63. Let E = 36.0 V, R0 = 50.0 , R = 150 , and L = 4.00 H. (a) Switch S1 is closed and switch S2 is left open. Just after S1 is closed, what are the current i0 through R0 and the potential differences vac and vcb? (b) After S1 has been closed a long time (S2 is still open) so that the current has reached its final, steady value, what are i0, vac, and vcb? (c) Find the expressions for i0, vac, and vcb as functions of the time t since S1 was closed. Your results should agree with part (a) when t = 0 and with part (b) when t S q. Graph i0, vac, and vcb versus time.
