Answer – Potential difference
emf generated (or potential difference) is given by
E = EReduction + Eoxidation
where
EReduction is expressed as reduction potential
Eoxidation is expressed as oxidation potential
E = EReduction – Eoxidation (when both ERed and Eox are expressed as reduction potentials)

Oxidation potential – The potential at which a species loses an electron
M —–> M+ + e-

Reduction potential – The potential at which a species gains an electron
M + e- ——> M-

Electrolysis – e.g water on electrolysis breaks up into hydrogen and oxygen.
