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 … Visa mer 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 when Visa mer Electromotive force is often denoted by $${\displaystyle {\mathcal {E}}}$$ or ℰ. In a device without internal resistance, if an electric charge $${\displaystyle q}$$ passing through that … Visa mer When multiplied by an amount of charge $${\displaystyle dQ}$$ the emf $${\displaystyle {\mathcal {E}}}$$ yields a thermodynamic work term $${\displaystyle {\mathcal {E}}\,dQ}$$ that … Visa mer Chemical sources The question of how batteries (galvanic cells) generate an emf occupied scientists for most of the 19th century.
