| Q. |
Off-set potential is |
| A. | difference in half-cell potentials between two electrodes |
| B. | sum of half-cell potentials between two electrodes |
| C. | average of half-cell potentials between two electrodes |
| D. | complement of half-cell potentials between two electrodes |
| Answer» A. difference in half-cell potentials between two electrodes | |
| Explanation: The difference in half cell potential that exists between two electrodes is called off-set potential. The differential amplifies used to measure potentials between two electrodes are generally designed to cancel the electrode offset potential so that only the signals of interest are recorded. | |
