Nikola Tesla
Pioneer of Alternating Current & Modern Electrical Systems
Why They Changed Society
Nikola Tesla's alternating current system is the reason you can flip a switch and have light. His polyphase AC system, including generators, transformers, and induction motors, won the 'War of Currents' against Edison's direct current and became the global standard for electrical power distribution. Every power grid, every electrical outlet, every appliance in the world runs on principles Tesla pioneered. Beyond AC, he developed foundational technology for radio, remote control, radar, and wireless communication. His vision of wireless energy transmission was decades ahead of its time. Tesla proved that a single inventor's brilliance could literally electrify civilization.
