  2. Galvanic cell - Wikipedia

    en.wikipedia.org/wiki/Galvanic_cell

    A galvanic cell or voltaic cell, named after the scientists Luigi Galvani and Alessandro Volta, respectively, is an electrochemical cell in which an electric current is generated from spontaneous oxidation–reduction reactions.

  3. Galvanic series - Wikipedia

    en.wikipedia.org/wiki/Galvanic_series

    The galvanic series (or electropotential series) determines the nobility of metals and semi-metals. When two metals are submerged in an electrolyte, while also electrically connected by some external conductor, the less noble (base) will experience galvanic corrosion. The rate of corrosion is determined by the electrolyte, the difference in ...

  4. Electrochemical cell - Wikipedia

    en.wikipedia.org/wiki/Electrochemical_cell

    An electrochemical cell is a device that generates electrical energy from chemical reactions. Electrical energy can also be applied to these cells to cause chemical reactions to occur. [ 1 ] Electrochemical cells that generate an electric current are called voltaic or galvanic cells and those that generate chemical reactions, via electrolysis ...

  5. Voltaic pile - Wikipedia

    en.wikipedia.org/wiki/Voltaic_pile

    The voltaic pile was the first electrical battery that could continuously provide an electric current to a circuit. [1] It was invented by Italian chemist Alessandro Volta , who published his experiments in 1799. [ 2 ]

  6. Electrochemistry - Wikipedia

    en.wikipedia.org/wiki/Electrochemistry

    An electrochemical cell is a device that produces an electric current from energy released by a spontaneous redox reaction. This kind of cell includes the Galvanic cell or Voltaic cell, named after Luigi Galvani and Alessandro Volta, both scientists who conducted experiments on chemical reactions and electric current during the late 18th century.

  7. Electric battery - Wikipedia

    en.wikipedia.org/wiki/Electric_battery

    Italian physicist Alessandro Volta built and described the first electrochemical battery, the voltaic pile, in 1800. [6] This was a stack of copper and zinc plates, separated by brine-soaked paper disks, that could produce a steady current for a considerable length of time. Volta did not understand that the voltage was due to chemical reactions.

  8. Thermogalvanic cell - Wikipedia

    en.wikipedia.org/wiki/Thermogalvanic_cell

    In electrochemistry, a thermogalvanic cell is a kind of galvanic cell in which heat is employed to provide electrical power directly. [1] [2] These cells are electrochemical cells in which the two electrodes are deliberately maintained at different temperatures.

  9. Electrolytic cell - Wikipedia

    en.wikipedia.org/wiki/Electrolytic_cell

    An electrolytic cell is an electrochemical cell that utilizes an external source of electrical energy to force a chemical reaction that would otherwise not occur. [ 1 ] : 64, 89 [ 2 ] : GL7 The external energy source is a voltage applied between the cell's two electrodes ; an anode (positively charged electrode) and a cathode (negatively ...
