What term describes the flow of electrons in a circuit?

The term that describes the flow of electrons in a circuit is current. Current is a measure of the amount of electric charge passing a point in a circuit per unit of time, typically measured in amperes (A). It represents the movement of electrons through the conductive pathway of a circuit, which is essential for the functioning of electrical devices.

Understanding current is crucial in the context of electric circuits because it dictates how much electricity is available for functioning devices and determines the overall efficiency of the circuit. High current can indicate that more electrons are flowing, which typically results in greater power usage by devices connected to the circuit. In contrast, resistance is a measure of how much a material opposes the flow of current, voltage refers to the electric potential difference that drives the current, and power is the rate at which energy is consumed or converted in a circuit, calculated from both current and voltage.
