What was the theory of Nicola Tesla?
Answers
Answer:
While still a student, Tesla began to think about the possibilities of alternating current (AC) electricity. AC electricity could generate high voltages for long distances without growing weaker. Tesla became convinced that AC was far more effective and less costly than direct current (DC) electricity, which was more common at the time.
After three years at the Graz Polytechnic Institute, Tesla stopped attending lectures. He left Graz in 1878 and began working as a draughtsman in Maribor. In 1880, Tesla moved to Prague to continue his studies at the Karl-Ferdinand University. Leaving Prague in 1881, Tesla moved to Budapest where Ferenc Puskás hired him to help install an Edison telephone exchange there. The Continental Edison Company sent Tesla to work in Paris and Strasbourg, where his work caught the eye of Charles Batchelor, head of Edison's operations in France, who invited Tesla to work for Edison in the United States. In 1884, he went to New York and immediately took a job with Edison, who recognized Tesla’s abilities but did not want to support his work on arc lighting. In 1886 Tesla founded the Tesla Electric Company, which funded his arc light experiments. More importantly, Tesla returned to his AC experiments and within two years had applied for more than thirty patents on his system.
After agreeing to a contract that turned over AC development and patents to the Westinghouse Corporation, Tesla became a wealthy man. He worked on a number of other inventions, including a transformer that changed low voltage to high voltage with a safe electrical current. This transformer is known as the Tesla coil.
