Nikola Tesla was a Serbian-American inventor and electrical engineer, best known for his work on alternating-current (AC) power systems. His inventions laid the foundation for modern electricity distribution.

Who was Nikola Tesla?

Born in 1856 in Smiljan (now Croatia), Tesla studied engineering and immigrated to the United States in 1884. He worked briefly with Thomas Edison before partnering with George Westinghouse to commercialise AC power.

What did he invent?

Tesla is best known for developing the AC induction motor, the rotating magnetic field, and the Tesla coil. He also held over 100 U.S. patents and contributed to radio technology and high-voltage engineering.

Why does his work matter?

Tesla’s AC power system made long-distance electricity transmission practical, powering modern grids including Canada’s. His legacy is studied in engineering and his ideas continue to influence power and radio technologies.

In short

  • Developed modern AC electricity supply system.
  • Invented the Tesla coil in 1891.
  • Worked with Thomas Edison and George Westinghouse.
  • Died in 1943 in New York City.
Canadian angle

Tesla is relevant to Canadian readers through his lasting influence on the electrical grid, power engineering, radio, and modern technology used in Canada, and his legacy is studied in science and engineering education.
