Nikola Tesla, a scientist of the 20th century takes alternating currents to his name. He was not involved with the scientist community as he did not get along with his co scientists. FBI took over his notes and documents which were sealed in 80 trunks for National security purposes after his death. His family could manage to get hold of few notes which were donated to Nikola Tesla museum. He was the one who brought alternating current to Edison’s knowledge. In 1884 Tesla went to U. S. to work with Edison. Tesla managed to build his first induction motor in 1883. In 1887 he set up his own laboratory and workshop in New York to enhance his motor. After a few months George Westinghouse secured Tesla’s patents and utilized his system for lightning at the1893 World Columbian Exposition in Chicago and won the contract to generate electricity at Niagara Falls, New York. Soon after this alternating current was supplied to the country and was used to power heavy machinery in all industries.
When we talk of alternating current the name of Charles Proteus Steinmetz is unforgettable, he was the one who studied alternating currents for years and got it patented as a system of distribution by alternating current (A/C power) on January 29,1895.
