What is the unit of measure for electrical power?

The unit of measure for electrical power is Watts, which is a fundamental concept in electrical engineering and physics. Power is defined as the rate at which electrical energy is transferred or converted. In terms of electricity, it can be calculated using the formula: Power (P) = Voltage (V) × Current (I), where Voltage is measured in Volts and Current is measured in Amperes. This relationship shows that power combines both the voltage across a circuit and the current flowing through it to give a measure of how much energy is being used or produced over time.

Understanding that Watts is the unit specifically related to power helps differentiate it from other electrical terms. For example, Volts represent the potential difference that drives electric current, Ohms measure resistance in a circuit, and Amperes indicate the flow of electric current. Each of these units plays a critical role in electrical circuits, but only Watts specifically quantify electrical power.
