John Hopkinson

John Hopkinson was a British physicist and engineer known for his contributions to electricity and magnetism. He developed important theories about how electrical systems work, including innovations in electrical measurement and power transmission. Hopkinson played a key role in understanding how alternating current (AC) systems operate, which are used for long-distance electricity transmission today. His work helped improve the efficiency and safety of electrical power systems, laying foundational knowledge for modern electrical engineering. Overall, he was a pioneer in understanding and advancing the science of electricity in practical ways.
