... Nikola set up his own lab and worked on sampling his AC motor. By 1888 he was ready to unveil his invention. George Westinghouse took particular interest in his ideas and appreciated the fundamentals of his patterns. Westinghouse bought Tesla’s patterns for $1 million and a $2.50 commission was to b ...

P6506 (a) When a current passes through a wire, a heating effect

... The DC distribution was supported by Edison. However, an ac system was strongly supported by Westinghouse to replace the existing DC distribution network. Finally the ac distribution method was adopted since transformers can be used with ac to step-up and step-down voltages, enabling transmission li ...
