Nikola Tesla was a Serbian-born American physicist, electrical engineer, and inventor. Tesla was one of the great pioneers of the use of alternating current electricity. Alternating current electricity changes in strength in cycles over time and is the type of electricity that power companies supply to homes today. Tesla invented the alternating current induction generator, a device that changes mechanical energy into alternating current electricity, and the Tesla coil, a transformer that changes the frequency of alternating current.
