The flow of electrons driven by electromotive force through a given resistance is expressed as which of the following?

The flow of electrons driven by electromotive force through a given resistance is known as current. In electrical terms, current refers to the rate at which electric charge flows through a conductor. It is typically measured in amperes (A). When there is an electromotive force, like voltage, that pushes electrons through a circuit, a current is established as the electrons move through the resistance present in the circuit.

Voltage, on the other hand, represents the potential difference that drives the current, while power is the product of voltage and current, indicating how much energy is being transferred per unit of time. Resistance is a property of materials that opposes the flow of current. Each of these concepts plays a critical role in understanding basic electrical principles, but for the specific definition concerning the flow of electrons, current is the most accurate term.
