Expert Answer:

Resistance is the property of boby by virtue of which it offers resistance to the flow of current. It changes with change in length , area of cross-section , temperature etc. whereas resistivity or specific resistance is a constant quantity for a given material. It is the resistance offered by unit length of conductor having cross section.
