History of electricity

The ancient Greeks, as light as a feather as a result of rubbing a piece of amber objects in a fur coat gözlemlemişlerdi won shrinkage. Electricity was first seriously examining scientist William Gilbert, 16 end of the century, did research on the relationship between magnetism, static electricity. Also identified as a negative and positive electrical charges made ​​to be named. Joseph Priestley in 1767, the electric charge each other, in inverse proportion to the square of the distance between them found they were making. 19th at the beginning of the century, Alessandro Volta invented the electric battery.

Davy, in 1808 the electric current carrying electrode separating two coal has managed to create an arc. And so it can be turned into electricity, light, or heat energy showed. In 1820, Hans Christian Orsted, near electric current passes through a conductor, a magnetic needle deflected by observing concluded that generates the magnetic field around the conductor of electrical current. Go beyond the walls of the laboratory to replace the electricity industry and the process of everyday life 19 began in the second half of the century. Zenobe-Théopline Gramme in 1873, showed that electrical energy can be transmitted efficiently through overhead lines. A. Edison's first electric production facilities in 1881 to establish the distribution network in New York, was the beginning of extensive use of electricity in homes and industry. Presence of an electron, the invention of the diode and triode lamp, marked the beginning of the development of electronics as a separate branch of science.
