Volta, when he made this great discovery, was following the work of Galvani, begun in 1786. But Galvani in his experiments mistook the effect for the cause, and so missed making the unique demonstration that two different metals immersed in a solution could set up an electric current.

Volta brought to the notice of the world the first means for obtaining a steady flow of electricity. The simplest facts of electro-magnetism, upon which much of the later electrical developments depend, remained entirely unknown until the first quarter of the nineteenth century. Davy first showed the electric arc or arch on a small scale between pieces of carbon. He also laid the foundation for future electrochemical work by decomposing by the battery current potash and soda, and thus isolating the alkali metals, potassiu
