In the circuit shown in Fig. P30.69,
Chapter 30, Problem 70P(choose chapter or problem)
CP In the circuit shown in Fig. P30.69, \(\mathcal{E}=60.0 \mathrm{~V}, \ R_{1}=40.0 \Omega, \ R_{2}=25.0 \Omega, \text { and } L=0.300 \mathrm{H}\). (a) Switch S is closed. At some time t afterward, the current in the inductor is increasing at a rate of di/dt = 50.0 A/s. At this instant, what are the current \(i_{1}\) through \(R_{1}\) and the current \(i_{2}\) through \(R_{2}\)? (Hint: Analyze two separate loops: one containing \(\mathcal{\varepsilon}\) and \(R_{1}\) and the other containing \(\mathcal{\varepsilon}, \ R_{2}\), and L.) (b) After the switch has been closed a long time, it is opened again. Just after it is opened, what is the current through \(R_{1}\)?
