उत्तर
The differences between the electrostatic potential of the positive and the negative end of an electric cell is the potential difference of the cell.
Explanation:
This represents the electrical pressure difference between the two terminals of the cell. It determines how much energy is supplied to the electric charges to move them through a circuit. Without this potential difference, electric current cannot flow.
