who invented the bulb and how?

Question

who invented the ligt bulb and how did he got the idea for it

Answer 1

Thomas Edison in the US. He was the first to market it successfully. When he realized that an electrical current running through metal caused it to glow, he set about to try to invent the electric light bulb. In the UK, Joseph Wilson Swan is credited.

Answer 2

The light bulb that we use today was developed by Thomas Edison - this
does not mean that he necessarily invented it though! Depending on where you
look, there are several people who are claimed to have invented it: Thomas
A. Edison (U.S.A.), Sir Joseph W. Swan (Britain), and A. N. Lodygin (Russia).
The way I understand it, both Edison and Swan were working on the light bulb
around the same time and it was Swan who was first to patent the light bulb.
About 10 months after Swan's patent, Edison read about Swan's invention in
Scientific American. Edison had been working on his own light bulb at the
time, and used Swan's idea of a carbon filament in his light bulb. Edison
then greatly improved the design of the light bulb and became quite famous
in North America for his "invention" - making a lot of money at the same time.
So, Edison's light bulb came to be with some help from Swan.

Answer 3

Mr. Thomas Edison did not invent electrical energy, you cant invent it, even if Mr. Benjamin Franklin, and others, chanced on that electrical energy replaced right into a usable project, Mr. Edison in basic terms invent contraptions that used it, the incandescent lamp(elementary bulb) and the DC present day (later used to ability electric powered chairs), so there ya have it, no human being invented it, yet people did use it for functional makes use of.

Answer 4

the idea of eletric bulb came from sir .humphry davy who first discovered the davy lamp .but the lamp was not efficient enough to give more light and was only for a shorttime. later it was thomas alva edison who spent lot of his in inventing the electric bulb.the principle of it is that when current is passed throgh a resistent wire the electrons hits the atoms of the element and produce heat and light .in an electic bulb they use tungsten filament as the resistent wire and it converts most of the collision energy into light rather heat .edison conducted more than 999 experiments to invent this...

Answer 5

Thomas Alva Edison

He faild 998 times before he invested the light bulb.

Answer 6

Thomas Alva Edison. He was laughed at by newspapers, for his idea of transforming electricity into light, but he probably was very knowledgeable of Physics. If you increase the temperature of a filament (through electrical resistance) eventually it will start to emit not only infrared radiation but also visible light. The trick was to get a filament that (in vacuum, so it wouldn't burn) could withstand the high temperature required. Allegedly he tried thousands of materials including a hair from one of his assistants' beard. Many people tried to make him give up, but he would reply: "Now we know thousands of materials that don't work. We just need one that does." Lamps today use Tungsten that fuses above 3 000 ºC.

Answer 7

Thomas Edison was the first to patent it. There were others working
on electric light at the same time, the concept wasn't his, however he was the first to get it to the market.

Answer 8

alwa Edison

He tried Fr 999 Times to do so

Answer 9

Heard that edison juz kept on trying many many times.
