Answer :
Final answer:
While at the University of Prague, Nikola Tesla developed designs for a brushless alternating current (AC) motor and a high-voltage electrical transformer. His inventions revolutionized the delivery of electricity and facilitated its use over vast distances.
Explanation:
While Nikola Tesla attended the University of Prague, he did not contribute directly to the improvement or repair of Edison's DC generators or power plants as implied in options A and B. However, he played a vital role in the advancement of electrical power systems. Tesla's significant contributions during this time include the design of the brushless alternating current motor (C), and high voltage electrical transformer (or coil) (D), the latter being a foundational aspect of modern electricity infrastructure.
Before Tesla, Thomas Edison had developed a DC (Direct Current) power system, but it had limitations in terms of distance. Nikola Tesla helped to offset these limitations by developing an AC (Alternating Current) system for the Westinghouse Electric & Manufacturing Company. His contributions transformed the use of electricity, allowing power supplies for lights and other equipment to extend for miles from the source.
