Question

Differentiate between resistance and resistivity 

Answer 1

Hey there ‼
____________________________________

RESISTANCE ➡
▶ Resistance is the property of a conductor to resist the flow of charges through it.
▶ Its SI unit is ohm.

RESISTIVITY ➡
▶ Resistivity is the electrical resistance per unit length and per unit of cross-sectional area.
▶ Its SI unit is ohm metre.

Hope my ans.'s helpful. (^-^)

Answer 2

Resistance is the obstruction offered to the flow of current by a conductor. 
Resistivity is the obstruction offered to the flow of current by UNIT AREA OF the conductor. 

So basically, resistance is the property of the object (say a copper  wire), whereas resistivity is the property of the substance (copper). 

And so resistance depends upon the properties of the object. 
Whereas resistivity depends upon the properties of the metal. 

hope it helps you.....
