∙ Volt is the electrical unit of voltage or potential difference (V).
∙V is related to Change in Potential Energy ΔU as
V=ΔUq
From above formula, We get 1 Volt potential difference when a change of 1 joule of Potential energy is there in moving a charge of 1 Coulomb.
Therefore, 1 Volt = 1 Joule/Coulomb.
