(a) Calculate the resistance of aluminum wire with a cross sectional area of 10 mm2 and length of 2 meters, the resistivity of Titanium is 0.027 Ohm*mm2/m. (b) If the resistivity of copper is much lower, 0.0171 Ohm*mm?/m, how long would a wire of copper, with the same 10 mm2 cross sectional area have to be to have the same resistance as the 2 meter long aluminum wire?
