    D₁ = L = 1 m

              i = 0,5 A

              V = 1,0 V

              A = 2,0 . 10^-7

     D₂ =  Hambatan jenis kawat . . . . ?

     D₃ =  R = ^{ρ L}/_A

              ^V/_i= ^{ρ L}/_A

              ¹/_0,5 = ^ρ1/_{2,0 . 10-7}

              2 = ρ . 5 . 10^-8

              ρ =  2 ÷ 5 . 10^-8        

            ρ =  4 . 10^-9 Ω m atau

       ρ =  40 .10^-8 Ω m
