The switch in the figure below is open for t < 0 and is then thrown closed at time t=0. Assume R = 4.00 k, L = 1.00 H, and  = 20.0 V. (a) Find the current in the inductor as a function of time t. (b) Find the current in the switch as a function of time t. (c) After a long time, the switch is thrown open once again. Find the current in the remaining loop as a function of time t.
