Ohm's law, named after its discoverer Georg Ohm [1], states that the potential difference between two points along a connected path and the current flowing through it are proportional at a given (i.e., fixed) temperature:
V=I.R
where V is the potential difference, I is the current, and R is a constant called the electrical resistance of the conductor.
The potential difference is the voltage drop from one point to a second point within the connected path of a conductor, and is sometimes designated by E or U instead of V. The unit of resistance is the ohm, which is equal to one volt per ampere, or one volt-second per coulomb.

It is applicable only when the current is steady and at a constant temperature

well uh if the voltage stays the same than if the resistance gets bigger, the current will drop. onl valid for resistance>0

R=V/I, V=IR, I=V/R
