A circuit element dissipates or produces power according to P=IVP=IV , where I is the current through the element and V is the voltage across it. Since the current and the voltage both depend on time...A circuit element dissipates or produces power according to P=IVP=IV , where I is the current through the element and V is the voltage across it. Since the current and the voltage both depend on time in an ac circuit, the instantaneous power is also time dependent.
