A 6Ω resistor, a 4 H inductor, and a 12 V battery are all connected in series, as shown above. The switch S, after being open for a long time, is closed at time t = 0. a. Determine the voltage across the inductor immediately after the switch is closed. b. Determine the current in the resistor after the switch has been closed for a long time. c. Write an equation for the voltage across the resistor as a function of time t after the switch is closed. d. On the axes below, graph the voltage across the resistor V versus time t, from t = 0 to t = 3 seconds

13(a). An inductor, battery, resistance, ammeter, and switch are connected in series. If the switch, initially open, is now closed, what is the final value of the current? Zero battery voltage divided by inductance, battery voltage times inductance, battery voltage divided by resistance. The current is doubled. The current is halved. The current is a factor times exp(-tc/t), where tc is the time constant. 13(b). A 13-V battery is connected in series with a switch, resistor, and coil. If the circuit's time constant is 1.2 x 10^-4 s and the final steady current after the switch is closed becomes 2.5 A, what is the value of the inductance? 3.9 x 10^-3 H 6.2 x 10^-4 H 2.3 x 10^-1 H 2.7 x 10^-3 H 2.3 x 10^-5 H
