Resitivity is a constant of proportionality.The S.I unit of resistivity is ohm metre. It is a characteristic property of the material.
The Conductors have very low resitivity whereas Insulators have high resistivity.It is denoted by p that is rho.
R=rho(p)l/A
Hope it's help u!!
Plz mark me as brainleist..
