George Simon Ohm was a German physicist who discovered the law, named after him, which states that the current flow through a conductor is directly proportional to the potential difference (voltage) and inversely proportional to the resistance.

While his work greatly influenced the theory and applications of current electricity, it was so coldly received that Ohm resigned his post at Cologne. Finally in 1842, his work began to be recognized and he was awarded the Copley Medal of the Royal Society of London and was made a foreign member a year later. The physical unit measuring electrical resistance was given his name.
