In 1884, Serbian engineer Nikola Tesla came to America with little more than the clothes on his back. Within 20 years, he developed the system that would provide electricity to every home in the nation; invented a type of motor that's still used in all sorts of electric devices; and came up with most of the components used in radio and television broadcasting. In this BrainPOP movie, you'll discover how Tesla's alternating current system displaced the direct current system developed by Thomas Edison, how his induction motor changed everything, and why he remained an obscure figure until just recently.
