Question

Difference between cell potential potential difference

Answer 1

The difference between electrode potentials of two electrodes of electrochemical cell when no current is drawn from the cell is known as 'Electromotive Force (EMF)' of a cell, while the difference between the electrode potential of two electrodes when the cell is sending current through the circuit is called 'Cell Potential or Potential Difference' of the cell. Hence EMF is the maximum voltage that can be obtained from a cell, while Potential Difference of a cell is always less than EMF of cell.

Answer 2

Answer:

The electrical potential difference is defined as the amount of work done to carrying a unit charge from one point to another in an electric field. In other words, the potential difference is defined as the difference in the electric potential of the two charged bodies. Unit: The unit of potential difference is volt.
