Resistivity is the physical property of a particular substance which is having particular dimensions.
Resistivity is only proportional to the nature and temperature of the particular material.
ρ = (R×A)/L
R = Resistance, L= Length, A = Cross-sectional area
The SI unit of resistivity is Ohms-meter.
Electrical resistivity measurement is used as a quality control test for calcareous soil.
