An inductor (L = 50 μH) is subjected to a time-varying current. The emf then produced by the inductor is graphed in Figure P21.70. The initial current is 40 mA. Plot the corresponding current as a function of time. Assume the potential of the supply voltage is positive so that a decrease in current generates a positive voltage drop across the inductor.
