Nikola Tesla

Nikola Tesla was a Serbian­ American inventor who discovered the basis for most alternating-current machinery. In 1884, a year after coming to the United States he sold the patent rights for his system of alternating-current dynamos, transformers, and motors to George Westinghouse. He then established his own lab where he invented, among other things, the Tesla coil, an induction coil widely used in radio.
