What term describes the rate at which electrical energy is used?

Power is defined as the rate at which work is done or energy is transferred over time. In an electrical circuit, it specifically describes the rate at which electrical energy is consumed, dissipated, or generated, and is measured in watts. The other options represent different electrical properties, not the rate of energy use. Current is the physical flow of electrons, voltage is the electrical pressure driving that flow, and resistance is the opposition to the flow. Only power describes the actual rate of energy consumption.
