History of the Creation of Lights – The principle behind the dynamo or electric generator was discovered by Michael Faraday and Joseph Henry. But the process of developing it into a practical electricity generator took years. Without dynamos for electricity generation, the development of electric motors has stalled, and electricity cannot be used as widely for transportation, manufacturing, or lighting as is used for today.
Arc light as a practical lighting tool was discovered in 1878 by Charles Brush, an Ohio engineer and a graduate of the University of Michigan. Others have attacked the problem of electric lighting, but the lack of suitable carbon is blocking their success. Charles Brush made several series lamps from one dynamo.
The first Brush lamp was used for street lighting in Cleveland, Ohio. Other inventors increase the light of the bow, but there are weaknesses. For outdoor lighting and for large hall lights, they function well, but arc lights cannot be used in small spaces. In addition, they are in series, that is, the current passes through each lamp in turn, and crashes to one toss the entire set of actions. All lighting problems in the room must be solved by one of the most famous inventors in America.
Thomas Edison, Beginning of the Story of the Discovery of Electric Lights
Thomas Edison arrived in Boston in 1868, practically penniless, and applied for a position as a night operator. In Boston he found people who knew something about electricity, and, when he worked at night and cut his sleep time, he found time to study. He bought and studied Faraday’s work.
Now his first diverse invention, an automatic voice recorder, for which he received a patent in 1868. This required him to travel to Washington, which he did by borrowing money, but he could not arouse interest in the device.
“After the voice recorder,” he said, “I found a stock ticker, and started a ticker service in Boston; has 30 or 40 customers and operates from a room above the Gold Exchange. ”Edison tried to sell this machine in New York, but he returned to Boston without success. He then discovers a duplex telegraph in which two messages can be sent simultaneously, but on the test, the machine fails due to the stupidity of the assistant.
Newark Store Project
Edison then tried to improve the automatic telegraph system (telegraph) used at the time and introduced it to England. He experimented with submarine cables and devised a quadruplex telegraphic system where one wire was made to do four jobs.
Both inventions were bought by Jay Gould, owner of the Atlantic and Pacific Telegraph Company. Gould paid 30,000 dollars for a quadruplex system but refused to pay an automatic telegraph. Gould had bought Western Union, his only rival.
“He then,” Edison wrote, “refused his contracts with automated telegraph people and they never received a cent for their cables or patents, and I lost three years of hard work. But I never held a grudge against him because he was so capable in his line, and as long as my part was successful, money with me was a secondary consideration. When Gould got Western Union, I knew that no further progress in the telegraph was possible, and I went into another route. “
Works for Western Union
In fact, however, lack of money forced Edison to continue his work for the Western Union Telegraph Company. He created a carbon emitter and sold it History of the Creation to Western Union for $ 1,000,000, paid in seventeen annual installments of $ 6,000. He made a similar agreement for the same amount for the electro-motograph patent.
He did not realize that this installment payment did not make good business sense. This agreement is typical of Edison’s early years as an inventor. He works only on inventions that can be sold to get money to meet payroll from different stores. Then the inventors employ keen entrepreneurs to negotiate agreements.
Invention of Electric Lights
Thomas Edison founded a laboratory and factory in Menlo Park, New Jersey, in 1876, and it was there that he invented the phonograph, which was patented in 1878. At that time at Menlo Park he began a series of experiments that produced incandescent lamps. Bandar Ceme Terbaik
Thomas Edison was determined to produce electric lights for indoor use. His first research was for a durable filament that would burn in a vacuum. A series of experiments with platinum wire and various refractory metals had unsatisfactory results. Many other substances have been tried, even human hair. Edison concluded that carbon of some kind was a solution rather than a metal. Joseph Swan, an Englishman really came to the same conclusion first.
In October 1879, after fourteen months of hard work and spending forty thousand dollars, carbon-cotton thread sealed in one of Edison’s balls was tested and lasted for forty hours. “If it’s going to burn forty hours now,” said Edison, “I know I can make it burn a hundred.” And he did. Better filament is needed. Edison found it in pieces of carbonated bamboo.
Edison developed his own type of dynamo, the largest ever made until then. History of the Creation Along with Edison’s incandescent lamps, it was one of the wonders of the Paris Electric Exhibition in 1881.
Installations in European and American plants for electricity service soon followed. Edison’s first large central station, supplying electricity for three thousand lights, was set up at Holborn Viaduct, London, in 1882, and in September of History of the Creation that year, Pearl Street Station in New York City, the first central station in America, was operated and began the period electricity industry.
