The energy per unit charge is called the potentialdifference.
Potential
The energy per unit charge is called the potentialdifference.
The SI unit of electric charge is called the coulomb. It is a derived unit, and is defined as the amount of charge moved by a steady state current of one ampere for one second. Alternatively, it is defined as the amount of charge across a capacitance of one farad charged to a potential of one volt. In terms of elementary charge, from nuclear physics, it is defined as the charge represented by about 6.24150965 x 1018 protons or electrons.

EMF is the energy per unit electric charge that is imparted by an energy source, such as an electric generator or a battery. As the device does work on the electric charge being transferred within itself, energy is converted from one form to another. This is the reason why it is called a force.The work done on a unit of electric charge or the energy gained by the unit charge is the electromotive force emf (or E) and is characteristic of any energy source capable of driving electric charge around a circuit. A common unit of electromotive force is the volt V, a unit equal to the difference in electric potential between two points in a conductor carrying a current of one ampere and dissipating one watt of power between the two points.
No, Coloumb is the unit of charge. The SI unit of energy is Joule.
Potential difference is defined as follows: every coloumb of charge that passes through this difference will gain (or lose, depending on direction and signs) 1 joule of energy. This unit, joule/coloumb, is simply called the volt.

electrical energy - energy made available by the flow of electric charge through a conductor;
Voltage.The correct term for the amount of energy per unit of charge is potential difference.Energy = Charge * VoltageSimple rearranging gives: Voltage = Energy / ChargeTherefore a volt can be defined as a "joule per coulomb".
Work is transfer of energy; thus, the unit of work is the same as the unit of energy.
