The unit of measurement for power is ___.

The unit of measurement for power is watts. Power, in the context of electrical systems, is defined as the rate at which electrical energy is transferred by an electric circuit. The watt, which is symbolized as "W", represents one joule of energy per second and quantifies how much electrical energy is used over a specific period of time in a circuit.

Understanding that power is calculated as the product of voltage (volts) and current (amperes) helps clarify why watts are the correct choice. Thus, while volt-hours measure energy consumption over time and amperes measure electric current, it is the watt that specifically measures power itself. This makes watts the definitive unit for expressing power in electrical applications.
