Which of the following terms is used to describe the rate at which electrical energy is transferred?

Power is the term used to describe the rate at which electrical energy is transferred or converted. It is calculated as the product of current (the flow of electric charge) and voltage (the electric potential difference). In electrical systems, power is measured in watts (W), where one watt is defined as one joule of energy transferred per second. This relationship is crucial in understanding how electrical devices operate and consume energy.

Current refers to the flow of electric charge in a circuit, measured in amperes, while voltage represents the potential difference that drives the current through the circuit. Energy, on the other hand, is a broader term that refers to the capacity to do work, measured in joules, but it does not specify the rate of transfer, which is where power comes into play. Therefore, power accurately represents the rate of energy transfer in electrical systems.
