The watt is the unit of electrical power.

The watt measures electrical power—the rate at which electrical energy is transferred or consumed. One watt equals one joule per second. In circuits, power is calculated as P = V × I, so multiplying voltage (volts) by current (amperes) gives power in watts. The other quantities are different units: resistance uses ohms, voltage uses volts, and current uses amperes. So the watt is specifically the unit of power.
