Nikola Tesla (10 July 1856 – 7 January 1943) was a Serbian American inventor, electrical engineer, mechanical engineer, and futurist best known for his contributions to the design of the modern alternating current (AC)electricity supply system. Tesla supported the now-accepted use of alternating current for most practical applications. In 1888 he built his first induction motor, which is the type of motor used in many domestic machines and appliances. He also invented a type of transformer, the Tesla coil, which produces enormous voltages and is used in radio technology.
