Alessandro Volta (1745-1827)


Alessandro Volta was an Italian scientist. In 1794, he explained why a frog's leg twitched when its muscles were touched with two different metals.
Volta showed that this was because an electric potential difference was produced between the two metals.
Potential difference is set up when there is a difference in charge between two point.
He then went on to make the first battery in 1800.
