Nikola Tesla was a Serbian-American inventor, electrical engineer, and physicist who is best known for his contributions to the design of the modern alternating current (AC) electricity supply system. He was born in 1856 in the village of Smiljan, in the Austrian Empire (now Croatia), and emigrated to the United States in 1884.
One of Tesla's most significant achievements was the development of the Tesla coil, a high-voltage, high-frequency transformer that is widely used in radio and television technology. He also conducted pioneering work in the fields of wireless communication, X-ray imaging, and robotics.
In addition to his work on AC power, Tesla made several other important contributions to the field of electrical engineering. He developed the first practical method for distributing electrical power over long distances, using high-voltage transmission lines. He also designed a system for generating and transmitting wireless power, which he demonstrated in a famous experiment in 1893 in which he lit vacuum tubes wirelessly, over a distance of 25 miles.
Despite his many accomplishments, Tesla faced many challenges and setbacks throughout his career. He was often in financial difficulty and struggled to get the recognition and funding he deserved. However, his work laid the foundation for many of the technological advancements we take for granted today, and he is now recognized as one of the greatest and most influential inventors in history.
