The EMF is the maximum voltage that the battery can deliver whereas the magnitude ofthe potential difference is always less than the maximum possible value of emf. The emfforce gains the electrical energy in the circuit whereas the potential difference loss the electrical energy in the circuit.

work done is use to move a unit of charge from one place to another called potential difference v=w/q
emf means electro motive force in this the source of energy is dynamo and battery it is also called electric potential
