copper wire has 172x108 resistivity with a length of 50m diameter of 2mm what is

aluminum is 2.82x10^-8 ohm-mAluminum with the same resistance as 50 meters of copper. (Resistance) = (Resistivity)(Length/Area) So if the resistivity changes by (2.82/1.72), then the length changes by (1.72/2.82). So the length of aluminum would be 50m(1.72/2.82) Length of aluminum would be 30.5 metersOther related question
