In the circuit shows in Fig. , E = 10 V, R1 = 5 Ω, R 2 = 10 Ω, and L = 5 H. For the two separate conditions, (i) switch S is just closed and (ii) switch S is closed for a long time, calculate a. current i1 through R1, b. current i2 through R2, c. current i through the switchs, d. the potential difference across R2, e. the potential difference across L, f. di 2/dt.
