Household wiring often uses 2.0 mm diameter copper wires. The wires can get rather long as they snake through the walls from the fuse box to the farthest corners of your house. What is the potential difference across a 19 m long, 2.0 mm diameter copper wire carrying an 9.0 A current? (Resistivity of copper = 1.7 x 10-8
