(a) Consider a 5-µH inductor to which a current source i(t) is attached, as shown in Figure (b). Sketch the inductor voltage and stored energy as a function of time.

(b) Let a voltage source v(t) shown in Figure (a) be applied to the 5-µH inductor instead of the current source in part (a). Sketch the inductor current and energy stored as a function of time.

(c) If three identical 5-µH inductors with initial current of 1 mA are connected (i) in series and (ii) in parallel, find the equivalent inductance for each case.
