WebThe cell potential (often called the electromotive force or emf) has a contribution from the anode which is a measure of its ability to lose electrons - it will be called its "oxidation potential". The cathode has a contribution based on its ability to gain electeons, its "reduction potential". The cell potential can then be written WebJan 24, 2024 · The electromotive force (abbreviated emf) or cell potential is the driving force. The emf of a cell is also known as cell voltage and is measured in volts \ ( (\text {V})\).
