The Alternating Current
Nikola Tesla invented the Alternating Current (AC Current) in 1888. The Alternating Current has direct current flowing continuously in one direction. It changes about 50-60 times per second which gives it more voltage and decreases power loss. Nikola Tesla developed the Alternating Current system by combining generators, motors and transformers that were held by 40 U.S patents that one of Nikola Tesla's friend George Westinghouse bought. Nikola Tesla's Alternating Current and Thomas Edison's Direct Current led between many wars of currents. They each were debating on how each other currents were dangerous and which was better to use. Edison referred to the Alternating Currents as "death currents" and showed how even an elephant was able to be taken down by the Alternating Current, proving it dangerous to use. However Nikola Tesla has won the "battle" therefor this was one of the biggest inventions of Nikola Tesla's inventing career and is still used today, while others are more upgraded. Edison's Direct Current only traveled in one direction while Tesla's Alternating Current reversed directions. Nikola Tesla's purpose of inventing the Alternating Current was to have a use of electricity supply. Later on, shortly before Nikola Tesla had died, Edison stated that his biggest mistake was to develop his Direct Current, rather than Tesla's "Alternating Currents."
