Ohm's law

Ohm's law says: The strength of the electrical current flowing through an object is proportional to the electrical voltage. More precisely: If the electrical resistance defined as the quotient of voltage to current strength is constant, i.e. independent of voltage and current strength, Ohm's law applies to the object; the object then has an ohmic behavior. The designation of the law honors Georg Simon Ohm, who was the first to conclusively prove this connection for some simple electrical conductors.
