Potential difference is the difference in electric potential between two points, which is defined as the work required per unit of charge to move between two points. V = W Q where W is work done in joule and Q is the charge in coulomb. Its unit is joule per coulomb. When 1 joule work is done to move 1 coulomb charge from one point to the another, the potential difference between the points is said to be 1 volt. Hence, voltage is equal to energy per unit charge.
