EDISON INVENTED THE ELECTRIC BULB IN 1879
In 1879 Edison invented an electric light bulb. After experimenting with flames from charred yarn, he settled on carbonized paper filament. In 1880, he began to produce light bulbs that could be used safely at home, selling them for $ 2.5 a piece. However, in 1878, Joseph Wilson Swan, an English scientist, also invented an electric light bulb. The bulb was glass and contained a charred filament inside. Swan blew the air out of the bulb; because the filament did not burn out in an airless environment. These two scientists decided to join forces and founded Edison and Swan Electric Lighting Company. In 1883 he made what was called the Edison effect, which was the biggest invention of his life; that is, found the electron emission of a heated filament in the molecular space. This event, which he discovered in 1883, formed the basis of hot cathode tubes. Later he managed to improve the production of the incandescent lamp. This enabled the light bulb to become widespread among the public.
