As we learnt in

Electrode Potential -

The potential associated with each electrode is known as electrode potential.

-

 

 We know that E cell  = Reduction potential of Cathode + Oxidation potential of Anode

                                   = Reduction potential of Cathode - Reduction potential of Anode

                                   = Eright - Eleft


Option 1)

E=E_{left}-E_{right}\; \;

This option is incorrect.

Option 2)

E=E_{left}+E_{right}\; \;

This option is incorrect.

Option 3)

E=E_{right}-E_{left}\; \;

This option is correct.

Option 4)

E=-(E_{right}+E_{left})

This option is incorrect.
