Voltaic
Pile.
Alessandro Volta (1745-1827) was a friend of Galvani’s although his ideas differed slightly. Volta believed that the results from Galvani’s experiment were due to the salt liquids of the frog’s insides completing a circuit with the metal electrodes and producing electricity. The electricity came form the two metal electrodes toughing in a moist atmosphere as opposed to Galvani who thought that the legs themselves were creating electricity.
Following Galvani’s experiment Volta built the worlds first battery in 1800, the Voltaic pile. It consisted of alternating layers of Zinc, Silver and a separator of blotting paper soaked in salt water.
