What is electomotive force (EMF) ?

Electromotive Force (EMF) is that the short sort of Electro drive which is that the driving force of the electrochemical cell.

EMF is that the electric potential between the electrodes of an electrochemical cell.

Electromotive Force
Electromotive Force EMF

EMF = E1 - E2


E1 is the electrode potential of the more negative metal (anode)

E2 is the electrode potential of the more positive metal (cathode)

Electrode potential is the development of potential difference in the interface of electrode and electrolyte(electrolyte basically is an ionic conductor), when a metal (electrode / electronic conductor) is immersed in an electrolyte.
