A 3.7 mH inductor is initially connected to a 4.6 V battery at t 0 through a 3.0 Q resistor. Once the inductor is fully energized, the battery is removed and the 3.0O resistor is connected between the two terminals of the inductor. Find the current flowing through the resistor 18.0 usec after the inductor begins to be de-energized.
