Behavior of an inductor when connected to a battery

1. An inductor is connected to the terminals of a battery that has an emf of 12.0V and negligible internal resistance. The current is 4.86mA at 0.725 ms after the connections is completed. After a long time the current is 6.45 mA. What is
a) The resistance R of the inductor?
b) The inductance L of the inductor?

Solution Preview

When the inductor is just connected, as the current starts to increase, the inductor opposes the increase in current by developing an opposite voltage across it and the current will be minimum, after a long time, the current eaches ...
