Answers
Answer:
The first electric light was made in the year 1800 by an English scientist named Humphry Davy. He experimented with electricity and invented an electric battery.
Much later, in the year 1860 an English physicist Sir Joseph Wilsom Swan was determined to derive a practical long lasting electric bulb.
In the year 1877, the American Charles Francis Brush manufactured some carbon arcs to light a public square in Cleveland, Ohio, USA.
The inventor Thomas Alva Edison, experimented with thousands of different filaments to find the right material 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.
In 1903, Willis. R. Whitney invented a treatment for the filament so that it would darken the inside of the bulb as it glowed. In 1910, William David Coolidge invented the tungsten filament which lasted even longer than the older filaments.
The incandescent bulb revolutionised the whole world.
