Question: 1 / 495

What is defined as the flow of electrons along a conductor?

Voltage

Current

The flow of electrons along a conductor is defined as current. Current is the measure of the flow of electric charge, which is primarily carried by electrons in a conductive material. It is quantified in amperes (A), representing the amount of charge that passes through a conductor over a specific period.

Voltage, on the other hand, refers to the electrical potential difference between two points in a circuit, providing the force that drives current through a conductor. Resistance is a measure of how much a material opposes the flow of current, while capacitance relates to the capability of a system to store an electric charge. Each of these concepts plays a critical role in understanding electrical circuits, but it is current that specifically indicates the movement of electrons.
