Expert Answer
The relationship between the terminal voltage and the EMF is given by the following equation:
In the above equation, V is the terminal voltage, 'I' is the current flowing through the cell, 'r' is the internal resistance, E is the electromotive force.
The electromotive force (emf) is the potential difference of a source when no current is flowing i.e the rated value of voltage which is written on its body.
Terminal voltage is the voltage output of a device is measured across its terminals i.e the actual voltage supplied by the battery after over coming its internal resistance.
