How is current defined in electrical terms?

Current in electrical terms is defined as the flow of electric charge. This flow typically occurs in a conductor, such as a wire, when there is a voltage applied across it. The movement of charge carriers, usually electrons, creates a current, which is measured in amperes (A). This concept is fundamental in understanding how electricity operates within circuits and various electrical devices.

The other options describe different electrical concepts. Measurement of electrical resistance pertains to how much the flow of current is inhibited by a material, while the amount of voltage applied indicates the electric potential difference that drives the current. The total energy produced in a circuit relates to the work done by the current over time, which involves both current and voltage but is not the definition of current itself. Thus, defining current as the flow of electric charge captures its essential role in electrical systems.
