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

In physics and electronics, power is defined as the rate at which work is done or energy is consumed over time. In an electrical circuit, it is the rate at which electrical energy is transformed into another form, such as heat, light, or radio waves. Power is measured in watts, where one watt equals one joule of energy per second. The other terms describe different electrical properties but not a rate of energy usage. Voltage is the electrical pressure or potential difference. Current is the volume of electrons flowing through the circuit. Resistance is the opposition to that flow.
