Question

What is a volt in physics?

Answer 1

Volt:

1. The Volt (often denoted by the symbol 'V') is a unit of electric potential difference (commonly abbreviated to voltage), electromotive force (commonly abbreviated to EMF), and electric potential.
2. According to the International System of Units (SI), one volt is equal to the difference in electric potentials between two given points in a wire carrying an electric current of magnitude 1 ampere and dissipating one watt of power between those two points.
3. It can also be defined as the potential difference that exists between two points and imparts one Joule of energy to each Coulomb of charge that passes through it.
