Chapter 30, Problem 28E(choose chapter or problem)
In Fig. 30.11, suppose that \(\varepsilon=60.0\) V, \(R=240\) \(\Omega\), and \(L=0.160\) H. Initially there is no current in the circuit. Switch \(\mathrm{S}_{2}\) is left open, and switch \(\mathrm{S}_{1}\) is closed. (a) Just after \(\mathrm{S}_{1}\) is closed, what are the potential differences \(v_{a b}\) and \(v_{b c}\)? (b) A long time (many time constants) after \(\mathrm{S}_{1}\) is closed, what are \(v_{a b}\) and \(v_{b c}\)? (c) What are \(v_{a b}\) and \(v_{b c}\) at an intermediate time when \(i=0.150\) A?
