Which unit is used to measure electrical power?

The unit used to measure electrical power is the Watt. Power in an electrical context is defined as the rate at which electrical energy is transferred by an electric circuit. One Watt is defined as one Joule per second and can also be expressed in terms of voltage and current as volts times amperes. This relationship highlights how power, voltage, and current are interconnected in electrical systems.

Ohms measure electrical resistance, volts measure electrical potential or voltage, and amperes measure electrical current. While these units are critical to understanding electrical circuits, they do not directly represent power, which is why the Watt is the correct unit in this context.
