e.m.f. of cell |
Terminal voltage of cell |
1.It is measured by the amount of work done in moving a unit positive charge in the complete circuit inside and outside the cell. |
1. It is measured by the amount of work done in moving a unit positive charge in the circuit outside the cell. |
2.It is the characteristic of the cell i.e., it does not depend on the amount of current drawn from the cell |
2. It depends on the amount of current drawn from the cell. More the current is drawn from the cell, less is the terminal voltage. |
3.It is equal to the terminal voltage when cell is not in use, while greater than the terminal voltage when cell is in use. |
3. It is equal to the emf of cell when cell is not in use, while less than the emf when cell is in use. |
