The generated voltage was directly related to the reactivity of the electrolyte with the metal.Davy understood that the actions of electrolysis and the voltaic cell were the same.At the receiving end, the wire would terminate in a jar filled with methane gas.To signal a coded event, an electrical spark would be sent by the wire to detonate the electric pistol. In 1791, while working at the University of Bologna, Luigi Galvani (1737-1798) discovered that the muscle of a frog contracted when touched by dissimilar metallic objects.One of the most remarkable and novel discoveries in the last 400 years is electricity.One may ask, “Has electricity been around that long?Volta (see Figure 2) then thought of using this invention to provide long distance communications, albeit only one Boolean bit.

[There are alternative explanations for the Parthian battery but it does work as a battery.France was one of the first nations to officially recognize Volta’s discoveries.France was approaching the height of scientific advancements and new ideas were welcomed with open arms.” The answer is yes and perhaps much longer, but the practical use of electricity has only been at our disposal since the mid to late 1800s.

One of the early electrical attractions that gained public attention was an electrically illuminated bridge over the Seine River during the 1900 World’s Fair in Paris. While constructing a new railway in 1936 near Baghdad, workers uncovered what appeared to be a prehistoric battery.Guericke was able to prove that the sparks generated were electrical in nature.
