While Thomas Edison promoted direct current Westinghouse advocated?

While Thomas Edison promoted direct current (DC) for electrical power distribution, George Westinghouse advocated for alternating current (AC) systems. AC could be transmitted over long distances more efficiently and at higher voltages than DC, making it a more practical choice for widespread electricity distribution. This rivalry culminated in the "War of the Currents," where AC ultimately became the dominant system for electrical power due to its advantages in scalability and cost-effectiveness. Westinghouse's AC system was eventually adopted for major projects, including the electrification of the 1893 World's Columbian Exposition in Chicago.
