volt

Also known as V

The volt (symbol: V), named after Alessandro Volta, is the unit of measurement of electric potential, electric potential difference (voltage), and electromotive force in the International System of Units (SI).

AI overview

A volt is the standard unit used to measure electrical pressure or force—the push that makes electricity flow through wires and devices. Understanding volts matters because it tells you how much electrical power a device uses and whether it's safe to use with a particular power source, like a battery or wall outlet.

Na física, o volt ou vóltio (símbolo: V, plural: volts) é a unidade que representa a tensão elétrica (ou diferença de potencial elétrico) do Sistema Internacional de Unidades (SI). O volt é o potencial de transmissão de energia, em joules, por carga elétrica, em coulombs, entre dois pontos distintos no espaço. Dizer que a tensão existente entre dois pontos corresponde a um volt é o mesmo que dizer que cada carga de um coulomb que se movimenta entre tais pontos transmite um joule de energia.
