Nikola Tesla (1856-1943) was a Serbian-American engineer and physicist. He studied mathematics and physics at the Graz University of Technology and philosophy at the University of Prague.
Tesla is responsible for how electricity flows today. He began studying electricity when sparks appeared as he stroked his cat. Additionally, when he was very young, he became seriously ill to the point of being near death, and his father promised him that if he recovered, he would send him to the university he had always wanted to attend. This is why Tesla studied physics at the Graz University of Technology.
Tesla’s idea was to find a way to make electricity reach the whole world for free. He worked on alternating current (AC) motors until he met Thomas Edison, who hired him to work on direct current (DC) dynamos. They each supported their own way of thinking and did not get along well. In fact, Thomas Edison tried to boycott Tesla’s work by highlighting the negative side of alternating current.
He also patented the rotating magnetic field, developed the three-phase system for electrical power transmission, and invented the Tesla coil, an induction coil used in radio technology. He is the inventor of the radio, although it was claimed that this invention belonged to Guillermo Marconi.
