What made Tesla great, however, was his amazing understanding of electricity. Remember that this was a time when electricity was still in its infancy. The lightbulb hadn't even been invented yet. When Tesla first came to the United States in 1884, he worked for Thomas Edison. Edison had just patented the lightbulb, so he needed a system to distribute electricity. Edison had all sorts of problems with his DC system of electricity. He promised Tesla big bucks in bonuses if he could get the bugs out of the system. Tesla ended up saving Edison over $100,000 but Edison refused to live up to his end of the bargain.

Tesla devised a better system for electrical transmission - the AC (alternating current) system that we use in our homes today. AC offered great advantages over the DC system. By using Tesla's newly developed Transformers, AC voltages could be stepped up and transmitted over long distances through thin wires.
