In is 1800 Count Alessandro Volta
(1745-1827) announced the results of his experiments
investigation Galvani's claims about the source of electricity in
the frog leg experiment. He undertook to prove that he could produce
electricity without the frog. He took the same bimetallic arcs (many
of them) and dipped them in glasses of brine.
This was Volta's Couronne des Tasses- his first battery.
pile was an improved configuration for a battery. With it he showed
that the bimetallic arcs were the source of electricity.
The unit of voltage is named after him.
