Answer:
Resistance is the property by the virtue of which a conductor tries to prevent the movement of electrons and hence prevent current flow.
Whereas Resistivity is a materialistic property dependent solely on the type of material.
The relationship between resistance and resistivity is :
R=ρ{
area
length
}
From this equation, we can easily understand that Resistance and resistivity are not numerically equal in all cases. They will be equal only when length and area are 1 unit respectively.
From this equation, we can easily understand that Resistance depends on the size of the conductor , whereas Resistivity (ρ) being is materialistic property is not dependent on size
