What term describes the flow of electrical charge in a conductor?

The flow of electrical charge in a conductor is defined as current. Current refers to the rate at which electric charge flows through a conductor, such as a wire, and is measured in amperes (A). When a potential difference (voltage) is applied across a conductor, it creates an electric field that pushes the charge carriers, typically electrons, through the conductor, resulting in a current. Understanding current is fundamental in electrical work, as it influences how circuits operate and how electrical energy is transmitted and utilized.

The other terms listed relate to broader electrical concepts but do not specifically describe the flow of charge. Voltage refers to the electric potential difference between two points, resistance indicates how much a material opposes the flow of current, and power relates to the rate at which electrical energy is transferred or converted. Thus, current is the distinct term that accurately captures the essence of electrical charge flow in a conductor.
