Ohm (Ω) Ohm (symbol Ω) is the electrical unit of resistance. The Ohm unit was named after George Simon Ohm. 1Ω = 1V / 1A = 1J ⋅ 1s / 1C 2. Table of resistance values of Ohm

Ohm is a unit of electrical resistance, named after Georg Simon Ohm, a German physicist who discovered Ohm’s Law, which states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points, provided the temperature and other physical conditions remain constant.

The ohm is defined as an electrical resistance between two points of a conductor when a constant potential difference of one volt, applied to these points, produces in the conductor a current of one ampere, the conductor not being the seat of any electromotive force.

Ohm's law is an empirical relation which accurately describes the conductivity of the vast majority of electrically conductive materials over many orders of magnitude of current. However some materials do not obey Ohm's law; these are called non-ohmic.
