The power of an electrical device can be calculated using the formula ( P = V \times I ), where ( P ) is the power in watts, ( V ) is the voltage in volts, and ( I ) is the current in amperes. For alternating current (AC) circuits, the formula can also include the power factor: ( P = V \times I \times \text{PF} ), where PF is the power factor. In cases of resistive loads, this simplifies to the same formula, as the power factor is 1.
