What is the term for the flow of electrons driven by electromotive force through a resistance?

The flow of electrons through a resistance driven by electromotive force is referred to as current. This refers to the movement of electric charge within a circuit. When a potential difference (voltage) is applied across a resistive component, it causes electrons to move, creating a current.

Current is measured in amperes (A), which quantifies the amount of charge that flows through a circuit per unit time. The presence of resistance in the circuit affects the amount of current that flows for a given voltage according to Ohm's law, which states that current equals voltage divided by resistance (I = V/R). Understanding this concept is crucial for analyzing and designing electrical circuits, as it allows electricians and engineers to predict how voltage and resistance will impact electrical flow.

While voltage is the potential difference that drives current, and power relates to the rate of energy transfer, it is the current that actually represents the movement of electrons through the circuit. Charge, on the other hand, refers to the property of matter that causes it to experience a force when placed in an electromagnetic field but does not specifically describe the flow associated with current.
