Answer
| E.m.f of cell | Terminal voltage of cell |
|---|---|
| It is measured by the amount of work done per unit change in moving a positive test charge in the complete circuit inside and outside the cell. | It is measured by the amount of work done per unit charge in moving a positive test charge in the circuit outside the cell. |
| It is the the characteristic of the cell, i.e., it does not depend on the amount of current drawn from the cell. | It depends on the amount of current drawn from the cell. More the current drawn from the cell, less is the terminal voltage. |
