Question

Explain the relation between the emf of cell

and the potential difference between the

terminals.​

Answer 1

Explanation:

V is the potential difference across the terminals of the cell and E is the emf of the cell.

The emf is set up by an electrochemical process within the cell.

The potential difference across the internal resistance of the cell is always Ir with the current flowing from the node at the higher potential to the node at the lower potential.
