Electromotive force or difference in potential expressed in volts.
The volt serves as the unit of measurement for electrical pressure, potential difference, or electromotive force. It quantifies the amount of force required to drive a current of one ampere through a resistance of one ohm. By definition, one volt represents the magnitude of potential difference that enables the flow of one ampere of electric current through a conductor with a resistance of one ohm.
The potential difference required to propel an electric current between two designated locations is referred to as voltage. A higher voltage exerts a stronger force, resulting in the movement of a greater number of electrons through a conductor within a specific time frame.
