Hii There!!!!
It states that, if physical condition of a conductor like :- length, thickness, nature of material etc. are kept constant.
Then, the potential difference ( V ) applied across the conductor is directly proportional to the current ( I ) flowing across it.
Mathematically, V = I × R

Ohm's law states that the current through aconductor between two points is directlyproportional to the voltage across the two points. Introducing the constant of proportionality, the resistance,[1] one arrives at the usual mathematical equation that describes this relationship:[2]
I=VR,{\displaystyle I={\frac {V}{R}},}
where I is the current through the conductor in units of amperes, V is the voltage measured across the conductor in units ofvolts, and R is the resistance of the conductor in units of ohms. More specifically, Ohm's law states that the R in this relation is constant, independent of the current.[3] Ohm's law is anempirical relation which accurately describes the conductivity of the vast majority ofelectrically conductive materials over many orders of magnitude of current. However some materials do not obey Ohm's law, these are called non-ohmic.
