SummaryGenerationOverviewHistoryNotation and units of measurementFormal definitionsIn (electrochemical) thermodynamicsDistinction with potential difference
The question of how batteries (galvanic cells) generate an emf occupied scientists for most of the 19th century. The "seat of the electromotive force" was eventually determined in 1889 by Walther Nernst to be primarily at the interfaces between the electrodes and the electrolyte. Atoms in molecules or solids are held together by chemical bonding, which sta…
