Nikola Tesla and George Westinghouse's AC system won over Thomas Edison's DC power system

During the late 1880s, electrical pioneers debated whether direct current or alternating current should power city electrical grids. Thomas Edison advocated DC power, which suffered severe transmission losses beyond a couple of kilometres. Nikola Tesla and George Westinghouse demonstrated that high-voltage AC could travel long distances through transformers, establishing AC as the global electrical distribution standard.
