What do volts represent in an electrical circuit?

Volts represent the force or pressure of electricity in an electrical circuit, which is also referred to as electric potential difference. This is essentially the measure of the energy per unit charge that is available to push electric charges through a circuit. When discussing electrical circuits, it's important to understand that volts indicate the potential energy that drives the movement of electrons.

In contrast, the total energy used by the circuit is measured in watt-hours or joules, not volts. Current, measured in amperes, represents the flow of electricity itself, while resistance, measured in ohms, quantifies how much a component opposes the flow of electric current. Thus, considering all these definitions, it's clear that volts directly correlate to the force propelling the flow of electricity in a circuit, making that the correct understanding in this context.
