Calculate the resistance of 1000m of 16mm2 (CSA) single copper conductor. Take to be 1.72 x 10-8 /metre.
+561 The formula for the resistivity of a wire is shown below.
𝜌=RAL
Where 𝜌 is resistivity, R is resisitance, A is cross-sectional area, and L is length. Simply plug the values you were given into the equation, and solve for R. Make sure that they are all in SI units.
1.72×10−8=0.000016R1000
R=1.075Ω
