3 You want to produce three 1.00-mm-diameter cylindri- cal wires, each with a resistance of 1.00 2 at room temperature. One wire is gold, one is copper, and one is aluminum. Refer to Table 25.1 for the resistivity values. (a) What will be the length of each wire? (b) Gold has a density of 1.93 × 10¹ kg/m³. What will be the mass of the gold wire? If you consider the current price of gold, is this wire very expensive?
