  • Resistance of a wire in Ω

    R = ρL/A

    ρ is resistivity of the material in Ω-m

    L is length in meters

    A is cross-sectional area in m²

    A = πr², r is radius of wire in m

    resistivity Cu .e- Ω-m or .e- ohm-mm

    .” = . m

    ft = m

    for each strand: Area = πr² = π(.)² = .e-m²

    R = (.e- Ω-m)()/(.e-) = ohms

    total resistance = / = . ohms
