A 3.7 mH inductor is initially connected to a 4.6 V battery at t D0 through a 3.0 Q resistor. Once the inductor is fully energized, the battery is removed and the 3.0 O 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.
