kg ⋅ m 2 ⋅ s −3 ⋅ A −1. The volt (symbol: V) is the unit of electric potential, electric potential difference ( voltage ), and electromotive force in the International System of Units (SI).
May 21, 2024 · Volt, unit of electrical potential, potential difference and electromotive force in the metre–kilogram–second system (SI); it is equal to the difference in potential between two points in a conductor carrying one ampere current when the power dissipated between the points is one watt.

Unit: Joule/Coulomb; Volt can also be defined as electric potential along a wire when an electric current of one ampere dissipates one watt of power. V = Dissipated Power/Current = P/I; Unit: Watt/Ampere; It can also be expressed as amperes times ohms. V = Current x Resistance = IR; Unit: Ampere – Ohm

The meaning of VOLT is the practical meter-kilogram-second unit of electrical potential difference and electromotive force equal to the difference of potential between two points in a conducting wire carrying a constant current of one ampere when the power dissipated between these two points is equal to one watt and equivalent to the potential ...
Volt is the electrical unit of voltage or potential difference (symbol: V). One Volt is defined as energy consumption of one joule per electric charge of one coulomb. 1V = 1J/C. One volt is equal to current of 1 amp times resistance of 1 ohm: 1V = 1A ⋅ 1Ω. Alessandro Volta.
Voltage, also known as (electrical) potential difference, electric pressure, or electric tension is the difference in electric potential between two points. [1] [2] In a static electric field, it corresponds to the work needed per unit of charge to move a positive test charge from the first point to the second point.
The volt (symbol: V) is the SI derived unit of electric potential difference or electromotive force (also known as voltage ). [1] . It is named in honor of the Italian physicist Alessandro Volta (1745–1827), who invented the voltaic pile, the first chemical battery . Definition.
