Working with inductors - but 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?
