Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points.

$I=V/R$

More specifically, Ohm's law states that the R in this relation is constant, independent of the current

Ohm unit: when the difference between the (+) and (-) poles is 1.0 Volt,

X# Ohms of resistence are needed to conduct 1 Amp
