Question
What are the differences between the potential difference and the emf of a cell?
Answer
| Electromotive force (EMF) | Potential difference |
|---|---|
| (i) It is the difference of potential between two electrodes of a cell or battery in an open circuit. | (i) It is the difference of potential between two electrodes of a cell or battery in a closed circuit. |
| (ii) It does not depend upon the resistance of the circuit. | (ii) It depends on the resistance of the circuit. |
| (iii) It is the cause. | (iii) It is the effect. |
