Explanation:
The electrical resistivity of a material is defined as the resistance of a conductor made of that material of unit length and unit cross-sectional area. ... A thicker wire has a larger cross-sectional area.
If I is the length of the conductor, A its area of the crosssection and R its total resistance then, Where P is a constant of proportionality and is called the electrical resistivity of the material of the conductor. The SI unit of resistivity is Ohm meter.
