Answer :

We know that energy has dimension of


In the unit 'eV', the charge part is not multiplied with potential. The charge is kept as 'e' and its value is not incorporated. As a result, energy has the same value of potential, because only the value of potential is used and not charge when we use the unit 'eV'. Thus, energy has the same value of potential.


This is not true when we use other units of energy like joule, where the value of charge is substituted and multiplied.
