Answer:
Electromotive force is defined as the electric potential produced by either electrochemical cell or by changing the magnetic field. EMF is the commonly used acronym for electromotive force. A generator or a battery is used for the conversion of energy from one form to another.
Explanation:
EMF is independent of circuit resistance: The potential difference depends on the re...
Electromotive Force: Potential Difference
EMF remains constant: Potential difference is not constant
It is represented by E: It is represented by V
Explanation:
a difference in potential that tends to give rise to an electric current.
Overview. Devices that can provide emf include electrochemical cells, thermoelectric devices, solar cells, photodiodes, electrical generators, transformers and even Van de Graaff generators. In nature, emf is generated when magnetic field fluctuations occur through a surface.
