If you use an extension cord, current travels from the 120 v outlet, along one wire inside the cord, through the appliance you've plugged into the cord, and back to the outlet through a second wire in the cord. the total resistance of the two wires in a light-duty extension cord is 0.44ω; the current through such a cord should be limited to 13 a. a 13 a shop vacuum is powered using this cord. what is the voltage drop across the vacuum?
