Multiple Choice

________ is the force that pushes electrons through a conductor.

Voltage is the electrical force that pushes electrons through a conductor. It’s the potential difference between two points that provides the “push” causing charges to move, much like pressure that drives water through a hose. The amount of current that flows depends on this push and the resistance the material offers, described by I = V/R. In practical terms, a voltage source supplies the push, while the conductor’s resistance and any circuit elements determine how much current flows. Current is the actual flow of electrons, resistance is what opposes that flow, and power is the rate at which energy is transferred. So the force that drives electrons through a conductor is voltage.
