Write differences between Electromotive force and …

Differences between the electromotive force and potential difference:

1. The electromotive force is the measure of energy that it gives to each coulomb of charge, whereas the potential difference is the amount of energy used by the one coulomb of charge.
2. The electromotive force is represented by the symbol ε whereas the symbol V represents the potential difference.
3. The electromotive force does not depend on the internal resistance of the circuit whereas the potential difference is directly proportional to the resistance of the circuit.
4. The electromotive force transfers the energy in the whole of the circuit. The potential difference is the measure of energy between any two points on the circuit.
5. The magnitude of the electromotive force is always greater than the potential difference when the circuit is unchanged but when the circuit is fully charged the magnitude of the potential difference is equal to the emf of the circuit.
