The electrical conductivity of copper and nickel material at room temperature are 6.0×107 (??m)-1 and 2.0×107 (??m)-1 , respectively. Copper and nickel form a solid solution at low concentrations at room temperature. If an alloy of nickel plus 5 atom % copper produced from these materials has an electrical resistivity of 11×10-8 ??m, what would be the electrical resistivity of an alloy of nickel plus 10-atomicpercent copper? You may assume that these are dilute solutions.
What will be an ideal response?
