Description: (British Physicist and Electrical Engineer Who Invented the Three-Wire System for Electricity Distribution)
John Hopkinson was a distinguished British physicist and electrical engineer celebrated for his significant contributions to the field. He held the position of President of the IEE (now the IET) on two occasions and was a Fellow of the Royal Society. Hopkinson is credited with inventing the three-wire (three-phase) system for electrical power distribution, for which he received a patent in 1882. His research in electromagnetism and electrostatics was groundbreaking, and he served as a professor of electrical engineering at King's College London. One of his notable achievements was the formulation of Hopkinson's law, a fundamental principle in magnetism.
