WebThe volt (symbol: V) is the unit of electric potential, electric potential difference ( voltage ), and electromotive force in the International System of Units (SI). [1] It is named after the Italian physicist Alessandro Volta (1745–1827). Definition [ edit] WebJun 21, 2011 · The SI unit of electric potential difference is the volt (V) 1 V = 1 W/A. The SI unit of electric resistance is the ohm (Ω). 1 Ω = 1 V/A. When spelled out in full, unit names are treated like ordinary English nouns.
WebElectric potential, denoted by V (or occasionally φ), is a scalar physical quantity that describes the potential energy of a unit electric charge in an electrostatic field. Va = Ua/q It is defined as the amount of work energy needed to move a unit of electric charge from a reference point to a specific point in an electric field.
In short, an electric potential is the electric potential energy per unit charge. This value can be calculated in either a static (time-invariant) or a dynamic (time-varying) electric field at a specific time with the unit joules per coulomb (J⋅C −1 ) or volt (V).
