WebApr 8, 2024 · The rate of doing work or the amount of energy transferred by a circuit per unit time is known as power in AC circuits. It is used to calculate the total power required to supply a load. Power factor: In an AC circuit, the power factor (PF) is defined as the ratio of real power (P) to apparent power (S). WebIt is convenient to use a similar formula for the average power dissipated in AC circuits when the current and voltage are in phase. However, the product of the raw voltage and current amplitudes (the zero-to-peak voltages and zero-to-peak currents), is twice the actual average power. To correct for this, we use rms voltages and currents.
