A
Work calculated from it is not the maximum work obtainable from the cell
B
It is maximum voltage obtainable from the cell
C
It is the potential difference between two electrodes when no current is flowing in circuit
D
It is responsible for the flow of steady current in the cell
Answer
Work calculated from it is not the maximum work obtainable from the cell
Explanation
Solution
E.M.F. is defined as the potential difference between two electrodes when current is flowing in circuit. It is the maximum work obtainable from the cell.
