Bright spark As a teenager, Alessandro Volta corresponded with physicist Giambattista Beccaria. He encouraged Volta to learn by experimentation. In 1791, Volta’s friend Luigi Galvani noticed that a frog’s legs twitched when they touched different metals, but mistook this for electricity inside living cells. Volta realized the frog was the conductor for electricity generated by the metal, so he experimented with what he called METALLIC ELECTRICITY. In his frog experiment, Galvani ir discovered that a pa of different metals . produced electricity
