Question

the difference in potential between the positive and the negative terminals of a cell is the ______ of that cell.​

Answer 1

Explanation:

Because of internal resistance of a battery, a part of EMF has been dropped within the cell. This voltage is not available in the terminal.

Total EMF of a battery = PD across terminal + lost voltage within the battery.

Answer 2

Answer:

the difference in potential between the positive and the negative terminals of a cell is the potential difference of that cell.
