Question
What is the difference between EMF and Cell potential (potential difference)?
| S. No. | EMF | Cell Potential (Potential difference) |
| 1. | EMF is the potential difference between two electrodes when no current is flowing in the circuit. | Cell potential measures the difference in the potentials of the two half-cells when electric current flows through the cell. |
| 2. | EMF is the maximum voltage which can be obtained from the cell. | Cell potential is always less than the maximum voltage obtainable from the cell. |
| 3. | EMF corresponds to the maximum useful work obtained from the galvanic cell. | Cell potential does not correspond to the maximum useful work. |
| 4. | EMF is measured by potentiometer | Cell potential is measured by using a voltmeter. |
