★The *resistivity* of a conductor is the resistance offered by a conductor of unit length and unit area of cross section.
OR
-it is the resistance offered by a conductor of (cubical) side of unit length when the current flows perpendicular to its opposite faces.
—the SI unit of Resistivity is ohm metre(Ω m).
★factors on which the resistance of a conductor depends are:–
a. Length of the conductor
b. Area of Cross-section
c. Temperature
d. Nature of material of the conductor.
In the picture above, you can find the Mathematical Expression of Resistivity.
#On the other, hand the property of a conductor due to which it opposes the flow of electric current through it is called Resistance.
The SI unit of Resistance is Ohm (Ω)
