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,
