Difference between resistance and resistivity.

1.	Difference between resistance and resistivity.
Answer» \tParameterResistanceResistivityDefinitionMaterial’s property that provides an obstruction to the flow of currentResistance of a material having specific dimensionsSymbolRPSI UnitOhmsOhms-meterFormulaR = V/I or, R = ρ(L/A) V = Voltage, I = Current, ρ = Resistivityρ = (R×A)/L R = Resistance, L= Length, A = Cross-sectional areaDependenceTemperature, Length, Cross sectional area of conductorTemperatureApplicationsResistance’s property is useful in sensors, fuses, heaters etcResistivity is effective as a quality control test\t
