Recall that the charge in a capacitor is given by (Q = CV). This is true at any time measured in the ac cycle of voltage. Consequently, the instantaneous charge on the capacitor is [q(t) = Cv_C(t) = CV_0, sin, omega t.] Since the current in the circuit is the rate at which charge enters (or leaves) the capacitor,
A capacitor is a device that stores energy. Capacitors store energy in the form of an electric field. At its most simple, a capacitor can be little more than a pair of metal plates separated by air. As this …

Most circuits, left undisturbed for su ciently long, eventually settle into a steady state. In a circuit that is in steady state, dv dt = 0 and di dt = 0 for all voltages and currents in the circuit|including those of capacitors and inductors. Thus, at steady state, in a capacitor, i = Cdv dt = 0, and in an inductor, v = Ldi dt = 0. That is, in ...
