What is the difference between resistance and resistivity of a conductor?
Asked by | 20 Dec, 2008, 11:19: PM
answered-by-expert Expert Answer

Resistance is the property of body by virtue of which it offers resistance to the flow of current. It changes with change in length , area of cross-section ,nature of material.

whereas resistivity or specific resistance is a constant quantity for a given material. It is the resistance offered by unit length of conductor having unit cross section. It varies with temperature.
