Question

State whether true or false :

The unit of voltage is $J{C}^{-1}$.

Answer 1

The given statement is "The unit of voltage is $J{C}^{-1}$. We have to see whether it is true or false. Since $J{C}^{-1}$ is equal to $JouleCoulom{b}^{-1}$. $Joule$ is the S.I unit of work and $Coulomb$ is the S.I unit of charge. So, $JouleCoulom{b}^{-1}$ means work done per unit charge which is equal to potential difference. So, $J{C}^{-1}$ is the unit of voltage. Given statement is True.
