what is the difference between EMF and potential difference??
Answer Posted / t.venkateswarlu
EMF(Electro Motive Force) is the voltage,that is converted from any other form of Energy to Electrical.For example,emf is used with Batteries, Generators, Motors (Back Emf).
Potential Difference between two points means difference between Potentials of two points.
