One volt is defined as a potential energy change of one joule per coulomb of charge: $V=(DeltaE_p)/Q=(12-8)/2=2$ $V$ .

A charge of 222 CCC is passing through points A and B on a circuit. If the charge's electric potential changes from 121212 JJJ to 888 JJJ, what is the voltage between points A and B?
