…used an electrostatic machine to make electricity that was discharged on gold electrodes in a Leyden jar. In 1800, Alessandro Volta invented the voltaic pile, while a few weeks later English scientists William Nicholson and Anthony Carlisle used it to electrolyse water. In 1806 Humphry Davy reported the…
