Hi
Resistivity is defined as resistance offered by a conductor unit length and unit area of cross. such that current flows perpendicular to it's opposite forces .
Resistance is defined as the opposition offered by a conductor to the flow of electron .
Resistance of a conductor can be changed but resistivity does not change.
Hope this helped you........

Resistivity is a measure of the resistance of a given size of a specific material to electrical conduction. ... Materials that conduct electrical current easily are called conductors and have a low resistivity. Those that do not conduct electricity easily are called insulators and these materials have a high resistivity.One of the major difference between the resistance and the resistivity of the material is that the resistance opposes the flow of free electrons whereas the resistivity is the property of the material which defines the resistance of the material having specific dimension.
