Georg Simon Ohm

Georg Simon Ohm (1787-1854), was a dedicated German physicist and mathematician who uncovered the fundamental law of electrical currents. Working as a secondary school teacher with self-built equipment, Ohm meticulously experimented with the conduction of electricity through different metals. In 1827, he published his findings, demonstrating a direct mathematical relationship between voltage, current, and electrical resistance, a principle now globally known as Ohm’s Law. Initially, his revolutionary work was rejected by the German scientific establishment, which favored a purely theoretical, non-experimental approach to nature. Recognition came later in his life when the Royal Society of London awarded him the Copley Medal. Today, the standard unit of electrical resistance, the ohm (Ω - Omega), is named after him. His persistence and clarity laid the indispensable foundation for all modern electrical engineering and circuit design.
