What is the electrical definition of the flow of electrons along a conductor?

The flow of electrons along a conductor is best defined as electricity. Electricity refers to the presence and flow of electric charge, which is primarily carried by electrons moving through a conductor. This movement of electrons constitutes the fundamental nature of electrical currents, where a flow through a conductive material occurs due to differences in electric potential.

Voltage is the measure of electrical potential difference between two points; it can't occur without the presence of electricity itself. Resistance, on the other hand, describes how much a material opposes the flow of electrical current; it is a factor that influences how easily electrons can flow but does not define their movement. Current specifically refers to the rate at which electric charge flows, but the term electricity encompasses the entire phenomenon, including both the flow of electrons and the force that drives their movement. Therefore, electricity is the most complete and accurate term relating to the flow of electrons along a conductor.
