In the circuit shown in the figure (figure 1), switch s is closed at time t0.
Alter being closed for a long time, the switch S in the circuit shown in Figure P33.14 is thrown open at t = 0. In the circuit, E = 24.0 V, RA = 4.00 kΩ, RB = 7.00 kΩ, and L = 589 mH. a. What is the emf across the inductor immediately after the switch is opened? b. When does the current in the resistor RB have a magnitude of 1.00 mA?
