WebElectrical Resistivity: 490 mΩ/mm Typical Mechanical Properties: Shear Modulus: 7.5 · 106 Modulus of Elasticity: 20 · 106 Ultimate Strength: 75 kpsi Yield Strength: 50 kpsi … WebThe electrical resistance of a wire is greater for a longer wire and less for a wire of larger cross sectional area. The resistance depend on the material of which it is made and can be expressed as: R = ρ L / A (1) where R = resistance (ohm, Ω) ρ = resistivity coefficient (ohm m, Ω m) L = length of wire (m) A = cross sectional area of wire (m2)
