define resistivity??

1.	define resistivity??
Answer» \tResistivity is the physical property of a particular substance which is having particular dimensions.\tResistivity is only proportional to the nature and temperature of the particular material.\tρ = (R×A)/L\tR = Resistance, L= Length, A = Cross-sectional area\t\t\tThe SI unit of resistivity is Ohms-meter.\t\t\tElectrical resistivity measurement is used as a quality control test for calcareous soil.\t It is a measure of resistance of a given size of a specific material to electrical condition.....HOPE IT WILL HELP U? pls answer
