RLC Circuits

In the circuit shown in Fig. 36-20 below, e = 10 V, R1 = 5 W, R2 = 10 W, and L = 5.0 H. For the two separate conditions (I) switch S just closed and (II) switch S closed for a long time, calculate (a) the current i1 through R1, (b) the current i2 through R2, (c) the current i through the switch, (d) the potential difference across R2, (e) the potential difference across L, and (f) di2/dt.
