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.
