A generating station is producing 2.00 106 W of power that is to be sent to a small town located 7.0 km away. Each of the two wires that comprise the transmission line has a resistance per kilometer of length of 5.00 10-2 /km.
(a) Find the power lost in heating the wires if the power is transmitted at 1300 V.


W

(b) A 120:1 step-up transformer is used to raise the voltage before the power is transmitted. How much power is now lost in heating the wires?
W
