On March 5, 188 years ago has died Alessandro Volta, Italian physicist who invented the electric cell and whose name was given drive voltage (volt).
Among his inventions are electrophonic Alessandro Volta, a tool for accumulation of static electricity - which underpins the capacitors used today electroscope (a tool which illustrates the potential differences) and the first electric battery in history, the so-called " voltaic pile "-" ancestor "batteries, which allowed the transformation of chemical energy into electrical energy.
This invention consists of a vertical column composed of a sequence of the disc copper / paper disc soaked in brine / zinc disc. At the ends of the column was attached by a wire from that produced a low-intensity electric current.
Volta described his invention as an "electric organ", similar to the fish-torpedo. The origin of the invention is the theory of "animal electricity" and the frogs experiences of another Italian physicist Luigi Galvani. Repeating his experiences, Volta has advanced the hypothesis that the origin of electricity occurred when the muscle is in contact with two different metals is not organic tissue, but contact between metals - and proved this assumption replacing the lock with tissue paper strips soaked in saline (conductor ) and gaining power, reversing Galvani's theory.
