One Volt is equal to –
A 1 Joule
B 1 Newton/Coulomb
C 1 Joule/Coulomb
D 1 Coulomb/Newton
One Volt is equal to –
A 1 Joule
B 1 Newton/Coulomb
C 1 Joule/Coulomb
D 1 Coulomb/Newton

Correct option is
C 1 Joule/Coulomb
– Volt is the electrical unit of voltage or potential difference (V).
\mathrm{V} is related to Change in Potential Energy \Delta \mathrm{U} as

    \[\mathrm{V}=\frac{\Delta \mathrm{U}}{\mathrm{q}}\]

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.
