How much work is done when one coulomb charge moves against a potential difference of 1 volt?

Given:  one coulomb charge moves against a potential difference of 1 volt

To find: work done

Solution:

We know the formula:

W = qV

Where q is the charge, W is the work done and V is the potential difference.

So, we get W = 1$\times$1

= 1 joule

Therefore the work is done in moving a charge of 1 coulomb across two points having a potential difference of 1 volt is 1 joule.
