Electromotive Force (E.M.F.) Vs Potential Difference

Electromotive Force (E.M.F.) or Cell Potential	Potential Difference
It is the potential difference between the two electrodes when no current is flowing in the circuit i.e., in an open circuit.	It is the difference of the electrode potentials of the two electrodes when the cell is sending current through the circuit.
It transmits current both inside and outside the cell.	It transfers current between any two points in the circuit.
E.m.f. is the cause.	Potential difference is the result.
It is maximum voltage obtainable from the cell.	It is less than the maximum voltage obtainable from the cell (i.e., e.m.f. of the cell).
The work calculated from e.m.f. is the maximum work obtainable from the cell.	The work calculated from potential difference is less than the maximum work obtainable from the cell.
It is responsible for the flow of steady current in the cell.	It is not responsible for the flow of steady current in the cell.
It does not depend on the resistance of the circuit.	Potential difference of two points depends on the resistance of those points.
The part of the circuit where electrical energy is created from any other energy then that part contains the source of Electromotive force.	Potential difference exists in the part of the circuit where electrical potential energy is transformed into another form of energy.
