Copper has high resistivity
WebFeb 7, 2024 · The resistivity of the material will not change (remain the same, ρ) as it is independent of the length or cross-section of the wire . So, All the wires would have the same resistivity. EXTRA POINTS: The resistivity of copper is generally given as 1.72 x 10-8 Ωm. Difference between resistivity and resistance: Download Solution PDF Share … WebUse the resistivity, ρ, to calculate the electrical conductivity, σ. Results Thicker wires will have lower resistances, but longer wires will have higher resistances. Copper has a lower resistivity and is a better conductor of electricity than iron. Why? The resistance of a wire increases with length.
