An extension cord is used with an electric weed trimmer that has a resistance of 18.3 ?. The extension cord is made of copper (resistivity 1.72 x 10-8 ohm m) wire that has a cross-sectional area of 1.60 x 10-6 m2. The combined length of the two wires in the extension cord is 88.5 m.
(a) Determine the resistance of the extension cord.
(b) The extension cord is plugged into a 120-V socket. What voltage is applied to the trimmer itself?
