What is the difference between electromotive force (emf) and potential difference (pd)?
1 Answer
The difference between electromotive force (emf) and the potential difference (pd) are as follows:
| SN | Electromotive Force (emf) | Potential Difference (pd) |
| 1. | The emf is the difference of potential between two electrodes of a cell in an open circuit. | Potential difference is the difference between any two points in a closed circuit. |
| 2. | It is greater than the potential difference during charging. | It is greater than emf during charging, |
| 3. | It is the cause of the potential difference. | It is an effort to make the electromotive force |
| 5. | It depends upon the internal resistance of the cell. | It depends upon the external resistance of the circuit. |
