History of the Invention of Electricity

The Greeks of 2000 years ago had known how to spark an electric spark. They do it with amber stones. The word electric comes from the Greek word electron meaning amber stone. Despite centuries of people playing with electricity, it was not until 1791 that a person discovered that electricity could move through a copper wire or other object that easily drains electricity. The inventor named Luigi Galvani, an Italian national. As he experimented, he accidentally connected a metal with the tip of another metal. The other end is connected to the nerves and muscles of a dead frog. This relationship creates a closed electric current.

Galvani thus discovered that a metal can flow an electric current from one end to the other. Ten years later, another Italian named Alessandro Volta produced the first electric battery. Batteries contain chemical devices that work with each other to create an electrical current through which data is streamed over the wire.

Therefore, the unity used to measure electrical power is called a volt, ie from the inventor Vota. Only then was an Englishman, Michael Faraday getting a way to create an electric current by rotating a disc between two magnetic poles. Machine made by Faraday is named dynamo or generator. This machine will run continuously during the caktram can rotate.
