What is the formula for power in an electrical circuit?

Mar 30, 2019 ... Let's take an example of a 60W light bulb that runs on 120V. Watts equals volts times amps, so if I write that as an equation: 60W = 120V * ? A. The volt-ampere is the unit of measurement for apparent power in an electrical circuit. It is the product of the root mean square voltage (in volts) and the ... Mathematically, the voltage is equal to the amperage times the resistance (V = AR, also referred to as the voltage formula), where the resistance is ... Mar 10, 2025 ...
