Ohm's law states that
V=I/R
where V=potential difference and R=resistance
.
.Electric current is the rate of flow of charge...Hope it helps you.

Ohms Law—
This law states that the current flowing through a conductor is directly proportional to the potential difference across the conductor.
I ∝ V
--------------------------------------------------
Electric Current—
It is defined as the rate of flow of charges per unit time.
I = Q /t
The SI unit for measuring an electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second.

Additive Information—
- A vacuum tube is a non-linear circuit. Its conductance changes with temperature, its current and voltage graph is not a straight line which implies that vacuum tube does not obey Ohm's Law.
- V = IR, R is contant known as Resistance for removing Proportionality.
