Starting from zero, an electric current is established in a circuit made of a battery of emf E, a resistor of resistance R and an inductor of inductance L. The electric current eventually reaches its steady-state value. What would be the effect of using an inductor with a larger inductance in this circuit?
A)The steady-state value of the current would be larger, but it would take the same amount of time to reach it.
B)The steady-state value of the current would be the same, but it would take more time to reach it.
C)The steady-state value of the current would be the same, but it would take the same amount of time to reach it.
D)The steady-state value of the current would be larger, but it would take more time to reach it.
E)The steady-state value of the current would be the same, but it would take less time to reach it.

The steady-state current is determined by Ohm's Law (I = E/R) and is independent of the inductance. However, a larger inductance increases the time constant (L/R), causing the current to take more time to reach its steady-state value.
