Answer: 1.Emf is the total voltage in the battery while the potential difference is the work done in moving a charge against the electric field between two specific points in the circuit. 2.Emf is always greater than the potential difference.

Explanation:
To me (electrical engineer since 1973), there is no difference. They are two different names for the same thing.
