Electric organ (biology) in research because of their resemblance to nerve-muscle junctions. The stack of electrocytes has long been compared to a voltaic pile, and may even have inspired the invention of the battery, since the analogy was already noted by Alessandro Volta. While the electric organ is structurally similar to a battery, its cycle of operation is more like a Marx generator, in that the individual elements are slowly charged in parallel, then suddenly and nearly simultaneously discharged in series to produce a high voltage pulse. To discharge the electrocytes at the correct time, the electric eel uses its pacemaker nucleus, a
History of chemistry succeeded in isolating the metal now known as tungsten by reduction of this acid with charcoal, and they are credited with the discovery of the element. Italian physicist Alessandro Volta constructed a device for accumulating a large charge by a series of inductions and groundings. He investigated the 1780s discovery "animal electricity" by Luigi Galvani, and found that the electric current was generated from the contact of dissimilar metals, and that the frog leg was only acting as a detector. Volta demonstrated in 1794 that when two metals and brine-soaked cloth or cardboard are arranged in a circuit they produce
