1.	What is the difference between resistance and resistivity??
Answer» \tSl. No.Differentiating PropertyResistanceResistivity1DefinitionResistance is the physical property of a substance because of which it opposes the flow of current i.e. electrons.Resistivity is the physical property of a particular substance which is having particular dimensions.2ProportionalityResistance is directly proportional to the length and temperature while it is inversely proportional to the cross-sectional area of the material.Resistivity is only proportional to the nature and temperature of the particular material.3SymbolRρ4FormulaR = V/I or, R = ρ(L/A) V = Voltage, I = Current, ρ = Resistivityρ = (R×A)/L R = Resistance, L= Length, A = Cross-sectional area5SI UnitsThe SI unit of resistance is OhmsThe SI unit of resistivity is Ohms-meter.\t
