A common 16 gauge medium duty extension cord -- the orange ones that you often see -- contains three copper wires each with a diameter of 1.29 mm. How much resistance would 15.2 meters of cord add to an appliance that you are using? The black and white conductors actually carry the current; the third ground wire is just a backup for the white wire. Use Google or the Resistance PowerPoint show to find the resistivity of copper. Express your answer in normal notation to three significant figures.
