(a) At t = 0, the current flowing in a 0.5-H inductance is 4 A. What constant voltage must be applied to reduce the current to 0 at t = 0.2 s? (b) Starting at t = 0, a constant 12-V voltage source is applied to a 2-H inductor. Assume an initial current of zero for the inductor. Determine the current, power, and stored energy at t = 1 s.
