In an AC circuits, current i (t) and voltage drops across various circuit elements, vc (t), vL (t), vR(t), are expressed as harmonic functions with different phases. Power dissipated by an element of a circuit is the time average of the current times the voltage drop across that element. For example, power dissipated by a capacitor is: Pav,C = time average of i(t)vc(t). In a series RLC AC circuit, electric power can be dissipated in: Only in the capacitor. Only in the inductor. Only in the resistor. In the capacitor and inductor. O In the capacitor and resistor. In the inductor and resistor. In all three elements.
