What does "OHM" mean??

The ohm is defined as the resistance between two points of a conductor when a potential difference of 1 volt, applied between these two points, produces in this conductor a current of 1 ampere, the conductor not being a source of any electromotive force.

OHM'S LAW

Ohm's law state that a current flowing through a conductor is directly proportional to its potential difference between its ends and inversely proportional to its resistance provided the physical condition such as the temperature remain constant.
