The circuit in the figure below consists of a resistor, an inductor, and an ideal battery with no internal resistance. At the instant just after the switch is closed, across which circuit element is the voltage equal to the emf of the battery? 1 2 3 33% 33% 33% 1 2 3 4 5 1. the resistor 2. the inductor 3. both the inductor and resistor
As the switch is closed, there is no current, so there is no voltage across the resistor.

After a very long time, across which circuit element is the voltage equal to the emf of the battery? 1 2 3 33% 33% 33% 1 2 3 4 5 1. the resistor 2. the inductor 3. both the inductor and resistor.
After a long time, the current has reached its final value, and the inductor has no further effect on the circuit.
