Edison was the first person in human history to use a large number of production principles and electrical engineering research laboratories to engage in invention patents and have a far-reaching impact on the world. The phonograph, movie camera and electric light he invented had a great influence on the world.
There were more than 2, inventions and more than 1, patents in his life. Edison was named the ninth among the 1 people who influenced the United States by the authoritative American periodical Atlantic Monthly.
in October, 1879, Edison finally succeeded in making an incandescent light bulb with carbonized fiber as the filament, which was called "carbonized cotton filament incandescent lamp". Subsequently, a large number of incandescent light bulbs were put into production, and a company was established to set up corresponding infrastructure such as power stations and transmission networks.
It soon made electric lights widely used in America. During this period, he constantly improved his technology, and finally decided to use tungsten wire as the filament, calling it "tungsten lamp", which has been used since then, and Edison has thus become a recognized inventor of electric light.

Speaking of Edison, everyone may have seen it in textbooks. Edison invented the electric light bulb, thus liberating mankind from the dark night. Scientifically speaking, there is no doubt about Edison's contribution to the world. When I was a child, many people regarded him as an idol, but most people didn't know Edison's true side. He was cruel and conceited, and once abused animals.
After Edison created the electric light bulb, he became a rich man at that time, and his company was also famous. Tesla, another great inventor, worked in Edison's company before he was famous, which changed Tesla's fate in this place and laid the foundation for Tesla's later invention of alternating current.
Later, Tesla and Edison disagreed. Edison firmly believed that direct current was the mainstream in the future, and frantically suppressed the alternating current proposed by Tesla. Of course, although both sides are for the benefit of the company, Tesla saw the future of alternating current, and Edison just made more money to promote his own direct current.
When Trass proves the convenience of alternating current to the world, Edison always likes to step on one foot. He takes all kinds of small animals, refutes the danger of Tesla alternating current with their lives, throws them into the current, and then tells people that this kind of electricity is fatal and may explode at any time.
After some alarmist talk and his own fame, people will follow Edison to see his DC, and then he throws animals into DC to prove the safety of DC.
