QUESTION 1. In the circuit shown below? the battery has been attached for a very long time and the current has attained a final constant value of I.

Suppose we suddenly switch the battery out of the circuit. The current eventually diminishes to zero. Suppose we then repeat the experiment with several inductors having the same overall geometry, but increasing the number of turns per unit length. For a fixed resistance R, the time it takes for the current to reach a value of (1/2) I

1. increases

2. decreases

3. is unaffected
