GENERAL KNOWLEDGE

Detailed explanation-1: -But further research on electromagnetism and any practical use of electricity would require a source of continuous current, which was not available until 1800, when Alessandro Volta invented the first electric pile, the forerunner of the modern battery.

Detailed explanation-2: -Volta found that electricity could be produced by just stacking alternate layers or discs of metals zinc and silver in a saltwater bath that would allow current to flow. This was the invention of the battery, the device described in Volta’s article on the electricity in 1800.
