Why did Nikola Tesla invented his devices?

Answer 1

With his newly created Tesla coils, the inventor soon discovered that he could transmit and receive powerful radio signals when they were tuned to resonate at the same frequency. When a coil is tuned to a signal of a particular frequency, it literally magnifies the incoming electrical energy through resonant action. By early 1895, Tesla was ready to transmit a signal 50 miles to West Point, New York.

In 1886, Tesla formed his own company, Tesla Electric Light & Manufacturing. The initial financial investors disagreed with Tesla on his plan for an alternating current motor and eventually relieved him of his duties at the company. Tesla worked in New York as a common laborer from 1886 to 1887 to feed himself and raise capital for his next project. in 1888. In the same year, he developed the principles of his Tesla coil, and began working with George Westinghouse at Westinghouse Electric & Manufacturing Company's Pittsburgh labs. In 1899, Tesla decided to move and began research in Colorado Springs, Colorado, where he would have room for his high-voltage, high-frequency experiments. n June 1902, Tesla's lab operations were moved to Wardenclyffe from Houston Street. Nikola began living in hotels in New york after that and began working in them by himself.

It my basic idea that Tesla was a Mentor to everyone in this world. Electricity is useless if it can't do anything, so in 1890, Tesla invented a motor to run on AC, the same type of motor used in every household appliance today. Scientists of the late 1880's were convinced that no motor could work with AC. After all, AC electricity reverses itself 60 times a second, so all previous motors would just rock back and forth 60 times a second. Tesla solved this problem and proved them all wrong.

Tesla developed and used florescent bulbs in his lab some 40 years before industry "invented" them. At the World's Fair, Tesla took glass tubes and bent them into famous scientists' names- the first neon signs. Tesla also designed the world's first hydroelectric plant at Niagara falls in 1895. Tesla also patented the first speedometer for cars in 1916.
