Georg Simon Ohm was a German physicist and mathematician best known for formulating Ohm's Law, which describes the relationship between voltage, current, and resistance in electrical circuits. His groundbreaking work laid the foundation for modern electrical engineering and significantly advanced the understanding of electrical circuits. Born in 1789, Ohm's contributions to science were initially met with skepticism, but his persistence led to recognition and respect in the scientific community. His influential book, Die galvanische Kette, mathematisch bearbeitet, published in 1827, detailed his findings and established him as a key figure in the field of electricity.
