In which unit is electrical power measured?

Electrical power is measured in watts. The watt is the standard unit for measuring the rate at which electrical energy is consumed or produced. One watt is defined as one joule of energy per second. This unit is crucial because it helps quantify how much electrical power devices use or generate, which is essential for understanding energy consumption, efficiency, and the capability of electrical systems.

The other units mentioned serve different functions in electrical theory. Hertz measures frequency, indicating how many cycles per second an alternating current or signal completes. Ohms measure electrical resistance, reflecting how much a material opposes the flow of electric current. Volts measure electric potential or voltage, which is the difference in electric potential energy per unit charge. Each of these units plays a vital role in electrical engineering, but watts are specifically focused on the measure of power.
