Question

An inductor is arranged in a circuit with the resistors, power supply and switch as shown. The switch is in position (a) for a long time before the switch is thrown into position (b). What is the current through the inductor immediately after the switch is thrown to (b)? Treat the inductor as ideal. 10 V 40 V R = 5 ? L = 0.50 H Choices: 2 A up 1 A up 16 A up 2 A down 1 A down 8 A up 16 A down 8 A down zero

Step 1

Initially, the switch is in position (a) for a long time, which means the circuit has reached a steady state. In a steady state, the inductor behaves like a short circuit because the current through it is constant. Show more…
