1 Resistance = R = potential drop across R / current passing thru R

resistivity is defined as row = R * A / L

R = resistance of conductor, A area of crosssection, L lenght of conductor

2 Resistance varies as size of conductor varies, diameter, length or area etc.

Resistivity is constant for a type of material like copper .

3 Resistance depends on resistivity , resistivity does not depend on R

4) Resistivity is the inherent property of the material lieke copper, rubber, glass, steel

Resistance is property of the conductor piece along with its shape

Similarity

both depend on temperature. Both increase with temperature.
