SUMMARY
The potential difference between two plates can be calculated using the formula V = W/Q, where V is the potential difference in volts, W is the work done in joules, and Q is the charge in coulombs. In this case, moving one coulomb with 120 joules of work results in a potential difference of 120 volts. This relationship is established by the definition of one volt being equivalent to one joule per coulomb.
