Distinguish between emf and terminal voltage of a cell.

Solution

Emf Terminal voltage
It is the maximum potential difference that can be delivered by a cell when no current flows through the circuit.  It is the potential difference across the terminals of the load when the circuit is switched on and a current flows through it.
It is represented by E and remains constant for a cell. It is represented by V and depends on the internal resistance of the cell.
  Is there an error in this question or solution?
