10 simple electric circuits with diagrams. however in an ac circuit the instantaneous values of the voltage current and therefore power are constantly changing being influenced by the supply so we can not calculate the power in ac circuits in the same manner as we can in dc circuits but we can still say that power p is equal to the voltage v times the amperes i.
