Question

An LR circuit contains a battery hooked up to an inductor and a resistor in series. As shown in the figure , a switch effectively removes the battery from the circuit. The switch is initially open

Immediately after the switch is closed (disconnecting the battery),across which circuit element is the voltage equal to the emf of the battery?
(a) the resistor

(b) both the inductor and resistor   

(c) the inductor

After a very long time, across which circuit element is the voltage equal to the emf of the battery?

(a) the inductor

(b) the resistor

(c) both the inductor and resistor

Explanation / Answer

Immediately after the switch is closed (disconnecting the battery),across which circuit element is the voltage equal to the emf of the battery?

Answer is a) resistor.

After a very long time, across which circuit element is the voltage equal to the emf of the battery?
