Question

An inductor is in a circuit with resistors and power supplies. The circuit is changed by throwing a switch, changing the voltage of a power supply or changing a variable resistor. Treat this change in the circuit as occurring very quickly.

What statement is true of the current in the inductor a long time after the circuit is changed? Treat the inductor as ideal.

(a.) Since = 0 at long times, the current in the inductor a long time afterwards must be the same as right before the circuit is changed.

Explanation / Answer

Since Ldi/dt=0 so voltage across inductor after long time will be zero so it will act like a wire

So option(b) is correct
