In electromagnetism and electronics, electromotive force (also electromotance, abbreviated emf, denoted $${\displaystyle {\mathcal {E}}}$$ or $${\displaystyle {\xi }}$$) is an energy transfer to an electric circuit per unit of electric charge, measured in volts. Devices called electrical transducers provide an emf by converting … See more Devices that can provide emf include electrochemical cells, thermoelectric devices, solar cells, photodiodes, electrical generators, inductors, transformers and even Van de Graaff generators. In nature, emf is generated … See more Electromotive force is often denoted by $${\displaystyle {\mathcal {E}}}$$ or ℰ. In a device without internal resistance, if an electric charge See more When multiplied by an amount of charge $${\displaystyle dQ}$$ the emf $${\displaystyle {\mathcal {E}}}$$ yields a thermodynamic work term $${\displaystyle {\mathcal {E}}\,dQ}$$ that is used in the formalism for the change in Gibbs energy when charge is … See more Although an electrical potential difference (voltage) is sometimes called an emf, however they are formally distinct concepts: See more In 1801, Alessandro Volta introduced the term "force motrice électrique" to describe the active agent of a battery (which he had invented around 1798). This is called the "electromotive force" in English. Around 1830, Michael Faraday established that chemical … See more Inside a source of emf (such as a battery) that is open-circuited, a charge separation occurs between the negative terminal N and the positive terminal P. This leads to an electrostatic field $${\displaystyle {\boldsymbol {E}}_{\mathrm {open\ circuit} }}$$ that … See more Chemical sources 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 … See more WebAug 7, 2024 · Mg(s) + 2 H + (aq) → Mg 2+ (aq) + H 2 (g) . a) Calculate the cell EMF for the reaction. b) Identify if the reaction is galvanic.
