Hello and welcome to TSR.

I assume you mean you want to know what the base units for potential difference are?

This is quite a nice question and not so difficult if you take things step by step:

To do this, start with the derived units of pd which is measured in Volts. and the definition of voltage is Joules/Coulomb of charge (JC-1) or V = E/Q

Now break down E and Q. Where you meet a derived unit, break it down further until you get to the base SI units and can go no further.

At that point replace the equations with their appropriate SI base units and rationalise where possible.
