Write Two Differences Between EMF And Potential Difference.

Electromotive force is the electric potential produced either by an electrochemical cell or by changing the magnetic field.

Differences between Electro-Motive Force(EMF) and Potential Difference

The differences between EMF and Potential Differences are as tabulated below –

Electromotive Force (EMF)	Potential Difference
EMF is the potential difference between two electrodes of a battery or a cell in an open circuit.	Potential Difference is the difference of potential between any 2 points of a closed circuit.
Electromotive Force is always greater than the potential difference between two points of a conductor.	The potential difference is always less than EMF.
EMF Formula: E = I * (R + r).	Potential Difference Formula: V = I * R.
EMF is caused by an electric, gravitational, or magnetic field.	Voltage is produced only in the electric field.
EMF is independent of resistance.	Potential Difference is dependent on resistance.
