Answer:
Electromotive force is defined as the electric potential produced by either electrochemical cell or by changing the magnetic field. ... Therefore, an electromotive force is a work done on a unit electric charge. Electromotive force is used in the electromagnetic flowmeter which is an application of Faraday's law

Answer:
The potential difference across the poles of a cell when no current is being taken from it is called the electromotive force (EMF) of the cell.
Explanation:
When current is being taken from the cell then its internal resistance added up to the circuits resistance. Internal resistance is maximum when there is no current draw from the cell.
