Explanation:
The average ac power is found by multiplying the rms values of current and voltage. Ohm's law for the rms ac is found by dividing the rms voltage by the impedance. In an ac circuit, there is a phase angle between the source voltage and the current, which can be found by dividing the resistance by the impedance
