The volt (symbol: V) is the unit of electric potential, electric potential difference (voltage), and electromotive force in the International System of Units (SI).
No, “volt” is not a standalone unit; rather, it is a unit of measurement for electric potential, electromotive force (emf), or electric potential difference. The volt is the SI unit of electric potential or electromotive force. It represents the difference in electric potential between two points of a conducting wire carrying a constant current of one ampere when the power dissipated between these points is one watt. In summary, “volt” measures electric potential difference or voltage, not a physical quantity like length or mass.
