  1. resistivity Copper is 17 nΩm

    1000' = 305 m

    1/8" = 0.003175 m

    Cross sectional Area = A = πr² = π(0.0015875)² = 7.917304e-6

    17 nΩm x 305 / 7.917304e-6 = 0.655 Ω


  2. A diameter of 1/8" is somewhere between #8 and #9 gauge wire.

    #8 = 128.5 diam. (mils), 16512 circular mils, 0.6405 Ω/1000'

    #9 = 114.4 diam. (mils), 13087 circular mils, 0.8077 Ω/1000'
