Chapter 26, Problem 12P
You are working at a company that manufactures electrical wire. Gold is the most ductile of all metals: it can be stretched into incredibly long, thin wires. The company has developed a new technique that will stretch 1.00 g of gold into a wire of length L = 2.40 km and uniform diameter. Your supervisor gives you the task of determining the resistance of such a wire at 20.0°C.
