who invented light bulb first?

Very good question, actually many people invented a light bulb here is some information for you!

The first 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.

In 1877, the American Charles Francis Brush manufactured some carbon arcs to light a public square in Cleveland, Ohio, USA. These arcs were used on a few streets, in a few large office buildings, and even some stores. Electric lights were only used by a few people.

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 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.

In 1802, Humphry Davy had what was then the most powerful electrical battery in the world at the Royal Institution of Great Britain. In that year, he created the first incandescent light by passing the current through a thin strip of platinum, chosen because the metal had an extremely high melting point.

Now ask us who invented the first COMMERCIAL light bulb.

depends on your definition of light bulb.

If you mean light caused by a heated piece of wire, then it was Humphry Davy in 1802

Joseph Wilson Swan in 1880 got a British patent on a on a light bulb, and demonstrated one in 1879.

If you mean who invented one that could be mass-produced and used in homes, then it was Edison in 1878

In between those, there were others who worked on developing the light bulb.

.

To the best of my knowledge it was indeed Thomas Edison, though Edison has another invention that is perhaps used even more frequently: the word 'hello'.

George Washington.

im pretty sure it was brittany spears. what r u dumb er something? u dnt kno who invented the light bulb? wow

pretty much anyone smarter than a 3rd grader knows it thomas edison

thomas edison
