The resistance and resistivity are directly proportional to each other.
Explanation:
The resistance is the force which restricts the flow of current. It is the proportionality constant between voltage and current in Ohm’s law. Because the Ohm’s law states that voltage in a circuit is directly proportional to the current flowing in it.
And resistance is the proportionality constant V = IR. The resistance depends on the length and cross section of the wire through which the current is made to pass. And, resistivity is the property of materials through which the current is passed.

Finally, this can be stated as the relation between resistance and resistivity.
