German physicist best known for Ohm's Law, the basic law of current flow. Educated in science by his father, a master locksmith, he worked as a schoolteacher before deciding to devote himself to research in physics. He began the studies leading to the formulation of his law in 1825 and discovered that the force of a current traveling through a conductor is a measure of the current...
