An aluminum wire 7.5 m long is connected in a parallel with a copper wire 6 m long. When a current of 5 A is passed through the combination, it is found that the current in the aluminum wire is 3 A. The diameter of the aluminum wire is 1 mm. Determine the diameter of the copper wire. Resistivity of copper is 0.017 μΩ-m Aluminum is 0.028 μΩ-m.
