How the Voltaic Pile works

Battery, 1800 For the battery we must thank the frog. In the 1780s, the Italian physicist Luigi Galvani discovered that a dead frog's leg would twitch when he touched it with two pieces of metal. Galvani had created a crude circuit and the phenomenon was taken up by his friend, the aristocratic Professor Alessandro Volta, whose voltaic cells stacked in a Voltaic pile amazed Napoleon. The pile was also the first battery, whose successors power more than a third of the gadgets on this list.
