Multiple Choice

_____ is a unit of electrical power.

Power in an electrical circuit is the rate at which energy is transferred or consumed, and its SI unit is the watt. In circuit terms, power equals voltage times current (P = V × I). That means if a device operates at 120 volts and draws 2 amperes, it uses 240 watts of power. The volt measures potential difference, the ampere measures current, and the ohm measures resistance, so they describe other electrical quantities rather than power. Because of that, watt is the unit that represents electrical power.
