What did Georg Simon Ohm discover?
Georg Ohm, in full Georg Simon Ohm, (born March 16, 1789, Erlangen, Bavaria [Germany]—died July 6, 1854, Munich), 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 …
What is Georg Ohm famous for?
Georg Simon Ohm had humble roots and struggled financially throughout most of his life, but the German physicist is well known today for his formulation of a law, termed Ohm’s law, describing the mathematical relationship between electrical current, resistance and voltage.
Did Ohm win a Nobel Prize?
His discoveries include Ohm’s law, Ohm’s torsion balance, a device used to measure current, and Ohm’s acoustic law, all of which were named after him. In 1841, he was awarded the Copley Medal by the Royal Society in London, an accolade which held the same prestige as a Nobel Prize today.
Did Georg Simon Ohm have a wife?
On June 23, 1800, he married Sabina Katherina Frasz, a hosier’s daughter, and on February 16, 1801, a daughter was born. Martin (senior) Ohm survived the birth of this daughter only a few weeks.
How did Georg Simon Ohm discover resistance?
Ohm demonstrated that there are no “perfect” electrical conductors through a series of experiments in 1825. Every conductor he tested offered some level of resistance. These experiments led to Ohm’s law.

What are the four laws of resistance?
4th law of resistance The resistance of the conductor depends upon the temperature of it. Resistance of metallic conductor increase with increase in temperature of the conductor. Where ρ is called rho . it is a constant and is known as resistivity or specific resistance of a material.
