Who invented the bulb and how?
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.
Who invent an eletric bulb?
Like most modern inventions, it was the work of many people over a number of years. The reference goes into in it detail. My money would be on Humphry Davy, who patented it. In 1802, Humphry Davy, demonstrated the first electric bulb. But it lasted only for minutes, and depended on batteries, the only available source of power. Joseph Swan in 1860, developed an improved light with carbonized paper filaments in an evacuated glass bulb. He patented it in 1880. Thomas Edison began research into developing a practical incandescent lamp in 1878. He developed a DC power generation system that made home and business use practical, and developed a bulb that lasted long enough to be useful.
What did people think about a electric light bulb when it first got invented by Thomas Edison?
See this link it is all fact. http://www.ideafinder.com/history/inventions/lightbulb.htm It tells you that Edison patented the light bulb in 1880 But it was patented 20 years before that by Swan, but that was a carbon filament and was useless.
Was invented first the telephone or the light bulb?
Hello, 1)The first telephone was invented by Alexander Graham Bell in the year 1876. 2)The first light bulb was invented by American inventor Thomas Alva Edison in year 1879.
What happened after Thomas Alva Edison invented the electric light bulb?
the correct answer is D. one reason it took so long is Tom wanted DC electricity and it really wasn't practical. A lot of debate went on before AC was adopted. Tom stood to benefit greatly if DC went through and was why he pushed it so.
Who Invented the light bulb?
The Invention of the Light Bulb: Davy, Swan and Edison 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.
Who invented the light and light bulb?
Well the invention of light bulb has some detailed history , it starts from the Italian inventor Alessandro Volta who developed the first practical method of generating electricity, the voltaic pile followed by several scientists who tried to perfect the invention generating artificial light. But it wasn’t till 1850 where English chemist Joseph Swan first laid his hands on creating the first light bulb but unfortunately for him the vacuum pumps of the day were not efficient in his time. Thomas Edison saw this flaw and fixed it with a filament. Eventually the two joined forces and formed Edison-Swan United, which became one of the world’s largest manufacturers of light bulbs, according to the Museum of Unnatural Mystery.Conclusion : Prototypes were built from the early 1800’s and were perfected by Thomas Edison and Joseph Swan.Thomas Edison was the one eventually credited for the invention thoughHope this answers your question
Who invented the bulb, Edison or Tesla?
None of the above. The light bulb was invented before Edison’s bulb. Tesla was not involved with the invention of light bulbs.Edison’s contribution was to make a high resistance bulb with adequate lifetime, so it could use around 110V instead of low voltage. He also set up the entire infrastructure, including bulb factories, switches, fuses, meters, and power plants.i.e. Edison made the light bulb a commercially successful product. Noboday else can claim that.
How exactly did Edison do 1000 trials to invent a lightbulb? How did every trial differ from the previous one?
Contrary to popular belief, Thomas Edison did not invent the first electric light bulb, but instead invented the first commercially practical incandescent light. Many earlier inventors had previously devised incandescent lamps, including Alessandro Volta's demonstration of a glowing wire in 1800 and inventions by Henry Woodward and Mathew Evans. Others who developed early and commercially impractical incandescent electric lamps included Humphry Davy, James Bowman Lindsay, Moses G. Farmer, William E. Sawyer, Joseph Swan and Heinrich Gobel. Some of these early bulbs had such flaws as an extremely short life, high expense to produce, and high electric current drawn, making them difficult to apply on a large scale commercially.After many experiments, first with carbon filaments in the early 1880s and then with platinum and other metals, in the end Edison returned to a carbon filament. Therefore, I'm guessing that the 1000 trials that he did all involved the same basic design but used a different light filament. The first successful test was on October 22, 1879; it lasted 13.5 hours. Edison continued to improve this design and by November 4, 1879, filed for U.S. patent 223,898 (granted on January 27, 1880) for an electric lamp using "a carbon filament or strip coiled and connected to platina contact wires". Here is a copy of the patent that was issued to him -Although the patent described several ways of creating the carbon filament including "cotton and linen thread, wood splints, papers coiled in various ways", it was not until several months after the patent was granted that Edison and his team discovered a carbonized bamboo filament that could last over 1,200 hours.Also, as a bonus, here is a photo of Thomas Edison's first successful light bulb model used in public demonstration in December 1879 -All the specific facts and pictures have been taken from WikipediaAll the above information is for the use in an answer to a Quora question, and thereby the spread of knowledge.
