Discovery of Volta


In the beginning of the year 1800 Volta made the first electric battery. He made it of copper and zink disks which he placed alternately. Above each pair of disks he placed a piece of wet cloth.
This first battery was a form of 'dry battery'.
Later Volta made a wet battery. Thus Volta showed that by bringing two different metals into contact he could produce an electrical charge. He discovered by experiments that if he placed copper and zink in sulphuric acid, he could produce a continuous flow of electricity.
He discovered the electric current and with this discovery a new era began in electric inventions.
