Halliday, Resnick & Walker — Induction and Inductance: Problem 14

14. In Fig. 30-26, \(\mathcal{E} = 100 \text{ V}\), \(R_1 = 10.0 \ \Omega\), \(R_2 = 20.0 \ \Omega\), \(R_3 = 30.0 \ \Omega\), and \(L = 3.50 \text{ H}\). Immediately after switch S is closed, what are (a) \(i_1\) and (b) \(i_2\)? (Let currents in the indicated directions have positive values and currents in the opposite directions have negative values.) A long time later, what are (c) \(i_1\) and (d) \(i_2\)? The switch is then reopened. Just then, what are (e) \(i_1\) and (f) \(i_2\)? A long time later, what are (g) \(i_1\) and (h) \(i_2\)?
