The unit for measuring power in electrical circuits is the watt. Power represents the rate at which electrical energy is consumed or generated and is calculated as the product of voltage and current. This means that watts quantify how much energy is used over a period of time, which is crucial in understanding electrical systems.

The other units mentioned—ohm, ampere, and volt—serve different purposes in electrical terminology. Ohms measure resistance, ampere denotes the flow of electric current, and volts signify electric potential or voltage. Each of these units plays a role in describing different aspects of electrical circuits, but when it comes to power specifically, the watt is the standard unit used.
