Georg Simon Ohm was a German physicist, best known for his “Ohm’s Law”, which states that the current flow through a conductor is directly proportional to the potential difference (voltage) and inversely proportional to the resistance. The physical unit of electrical resistance, the Ohm (symbol: Ω), was named after him.

Ohm died on July 6, 1854. He was 65 years old. The physical unit of electrical resistance, the Ohm (symbol: Ω), was named in his honor.
