Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality.
The following equation is known as Ohm's law:
I = V / R
You can also write Ohm's law as
V = I * R
You can also write Ohm's law as
R = V / I
Ohm's law states that the R in this relation is constant, independent of the current
