Explanation:
Electrical resistance is directly proportional to length and is inversely proportional to the area of cross section of the conductor. It also depends upon the material of the conductor. It changes as length, area and material changes. But resistivity depends only on the material of the conductor. It doesn't depend upon the length and area of the conductor.
