SUPPLEMENTARY TEXT. EDISON'S LIGHTING SYSTEM

Only at the end of the 19th century electricity began to play its part in modern civilization. The man who achieved more in this field of practical engineering than any of his contemporaries was the American inventor, Thomas Alva Edison. He became interested in the problem of electric lighting. He knew what had been done in the field of electric lighting before his time, and he had seen some devices of his contemporaries, such as arc-lamp illuminations, which had been installed here and there. Two sticks of carbon (вугільний электрод), nearly touching, can be made to produce an electric arc which closes the circuit. Many scientists and in­ventors working in this field knew that only incandescent (раскаленный) electric light — produced by some substance glowing (светящееся) in a vacuum so that it cannot burn up — could be used instead of gas lighting.

Edison put his laboratories to the task of developing such a lamp. His first experimental lamp appeared in 1879. Its light was yellowish and it worked for forty hours; the incan­descent electric lamp was born.
