1ohm
1ohm is a unit of electrical resistance. It is defined as the resistance between two points of a conductor, when a constant potential difference of one volt applied between these points produces in this conductor a current of one ampere. This definition is based on Ohm's Law, which states that the voltage across a resistor is directly proportional to the current flowing through it, with the resistance being the constant of proportionality.
The ohm is named after Georg Simon Ohm, a German physicist who discovered Ohm's Law in 1827.
The ohm is a fundamental unit in electrical engineering and physics. It is used in calculations involving
