It made people not need candles and oil lamps as much after Thomas Edison perfected the filament to burn up tp 1500 hours.
The first incandescent electric light was made in 1800 by Humphry Davy, an English scientist. 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) was determined to devise 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.
Lewis Howard Latimer (1848-1928) improved the light bulb by inventing a carbon filament (patented in 1881); Latimer was a member of Edison's research team, which was called "Edison's Pioneers." In 1882, Latimer developed and patented a method of manufacturing his carbon filaments.
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.
he stuck it up his butt to see if it would work and it did work and they have the one he stuck up his butt in a museum in California.

The invention of the light bulb made it possible to work longer hours. It increased safety in the workplace. The light bulb replaced oil lamps in homes. The oil lamps were fire-hazards. People found that they could enjoy leisure activities such as reading at night time.
cause it help reduce crime rate
So they can use it... :p it's simple... XD mark me as not helpfull!!
for the electrical machinery.
why were canals important in the first industrial revolution what problem did they solve and how was this accomplished
the water wheel changed the industrial revolution akot. this was a cheaper way to make electricity and cheaper.

The Industrial Revolution
a
The most important invention during the Industrial Revolution is the steam engine. Also the telegraph was a really important tool which was invented during the Industrial Revolution.
The French Revolution and Industrial Revolution in a close tie
Probably either the French Revolution or the American Revolution
It was an important part of the Industrial Revolution.
He was important in the industrial revolution.
