Definition. One volt is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points. [2] . It can be expressed in terms of SI base units ( m, kg, s, and A) as.

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 is defined as the potential difference across a conductor when a current of one ampere dissipates one watt of power. Hence, it is the base SI representation m 2 · kg · s −3 · A −1, which can be equally represented as one joule of energy per coulomb of charge, J/C.
The volt is a unit by which we measure something. Both electric potential and voltage are things we measure and the volt is the unit of measure for both. The symbol for the unit volt is written with a V (9 volts or 9 V). When voltage is used in a formula, it can be typeset in italics, e.g., , or written in cursive.
The volt-ampere (SI symbol: VA, sometimes V⋅A or V A) is the unit of measurement for apparent power in an electrical circuit. It is the product of the root mean square voltage (in volts) and the root mean square current (in amperes). Volt-amperes are usually used for analyzing alternating current (AC) circuits.
The Chevrolet Volt is a plug-in hybrid car that was manufactured by General Motors, and also marketed in rebadged variants as the Holden Volt in Australia and New Zealand and the Buick Velite 5 in China, and with a different fascia as the Vauxhall Ampera in the United Kingdom and as the Opel Ampera in the remainder of Europe.
Volt (disambiguation) Look up volt or Volt in Wiktionary, the free dictionary. Volt (symbol V) is the SI derived unit for electromotive force and potential difference, named after Alessandro Volta. Volt or Volts may also refer to: Electrical measurement. electron volt (eV), a unit of energy in physics.
