INCANDESCENT LIGHT BULB
Humphry Davy, an English scientist, made the first incandescent electric lamp in 1800. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. This is called an electric arc.
Much later, in 1860, the English physicist Sir Joseph Wilson Swan (1828-1914) made a practical, long-lasting electric light. He found that a carbon paper filament worked well, but burned up quickly. In 1878, he demonstrated his new electric lamps in Newcastle, England.
The inventor Thomas Alva Edison (in the USA) experimented with thousands of different filaments to find just the right materials to glow well and be long-lasting. In 1879, Edison discovered that a carbon filament in an oxygen-free bulb glowed but did not burn up for 40 hours. Edison eventually produced a bulb that could glow for over 1500 hours.
In 1903, Willis R. Whitney invented a treatment for the filament so that it wouldn’t darken the inside of the bulb as it glowed. In 1910, William David Coolidge (1873-1975) invented a tungsten filament, which lasted even longer than the older filaments. The incandescent bulb revolutionized the world.
WORDS:
Incandescent lamp – лампа накаливания
To glow – светиться
Long-lasting – долговечный
Filament – нить накала
Oxygen-free – бескислородный
Eventually – в конечном счёте
Bulb- лампочка
Treatment – обработка
Electric arc – электрическая дуга

I.
Гэмфри Дэви, английский ученый, сделал первую электрическую лампу накаливания в 1800 году. Он экспериментировал с электричеством и изобрел электрическую батарею. Когда он подключал провода к его батарее и кусочку угля, то уголь светился, производя свет. Это называется электрическая дуга.
Много позже, в 1860 году, английский физик сэр Джозеф Уилсон Суон (1828-1914) добился практического, длительного электрического света. Он обнаружил, что нить накала копировальной бумаги работала хорошо, но быстро сгорала. В 1878 году он продемонстрировал свои новые электрические лампы в Ньюкасле, Англия.
Изобретатель Томас Алва Эдисон (в США) экспериментировал с тысячами различных нитей накаливания, чтобы найти только те правильные материалы, которые светятся хорошо и являются долговечными. В 1879 году, Эдисон обнаружил, что углеродная нить в бескислородной лампочке светилась, но не сгорала в течение 40 часов. Эдисон, в конце концов, изготовил лампочку, которая могла светиться в течение более 1500 часов.
В 1903 году Уиллис Р. Уитни изобрёл обработку для нити накаливания, в результате чего она не будет темнеть внутри лампочки, когда светилась. В 1910 году, Уильям Дэвид Кулидж (1873-1975) изобрел вольфрамовую нить, которая служила даже дольше, чем прежние нити. Лампа накаливания произвела революцию в мире.
