An aluminum wire 8 m long is connected in parallel with a copper wire 6 m long. When a current of 10 A is passed through the combination, it is found that the current in the aluminum wire is 4 A. The cross-sectional area of the aluminum wire is 1 mm2. Determine the cross-sectional area of the copper wire.
The resistivity of copper is 0.017 µΩm
The resistivity of aluminum is 0.028 µΩ m.
