Answer:
Resistivity [tex]\rho =\frac{RA}{l}[/tex]
It depends upon cross sectional area and length of material
Explanation:
The resistance of any material is given by [tex]R=\frac{\rho l}{A}[/tex], here [tex]\rho[/tex] is the resistivity of material , l is length of material and A is cross sectional area
So resistivity [tex]\rho =\frac{RA}{l}[/tex]
So resistuivity of any material depends upon area of cross section and length of material
If cross sectional area will be more then resistivity will be more. And is length of the material will be more then resistivity will be less
