WebResistivity and Conductivity. The electrical resistance of a wire would be expected to be greater for a longer wire, less for a wire of larger cross sectional area, and would be expected to depend upon the material out of which the wire is made. Experimentally, the dependence upon these properties is a straightforward one for a wide range of conditions, … WebFeb 2, 2024 · Resistivity ρ, unlike resistance, is an intrinsic property of a material.It means that it doesn't matter whether the wire is thick or thin, long or short. The resistivity will always be the same for a specific material, and the resistivity units are "ohm meter" (Ω × m).The higher the resistivity is, the more difficult it is for the current to flow through a wire.
