Historical origin of the battery pack

- Aug 19, 2019-

Now we think that electricity is brought to us through the wall socket. However, there was no power grid in 1800, and the initial electrical experiment was carried out using the current generated by the battery pack.

At the time, the first battery pack was made by the Italian physicist Alessandro Volt.

His compatriot, biologist Lucy Galvani, noticed a strange phenomenon when dissecting a frog. When he touched the dead animal's legs with some metal, they twitched.

Volt believes that twitching is caused by the current generated by the metal. He started experimenting at the end of the 18th century.

He found that he could generate electricity by chemically reacting two metals called "electrodes" with certain solutions. He put these parts together and made the first battery pack.

Volt called his battery pack "heap" because it is a pile of zinc and copper discs separated by a gasket of a weak solution of salt or acid. When a metal wire is connected to the upper and lower circular plates, current flows through the metal wires.

In the earlier experiments of Galvani, the frog's body behaved like a wet cloth pad, allowing current to flow.

Volt's work is of great value to modern physics. All subsequent developments from electric motors to generators are derived from it.

Later, scientists used volts to name one of the standard electrical units, the potential unit, and gave him a high honor in recognition of his contribution.
