A generating station is producing 2.00 106 W of power that is to be sent to a small town located 8.0 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 used to heat the wires if the power is transmitted at 1300 V.

W

(b) A 50:1 step-up transformer is used to raise the voltage before the power is transmitted. How much power is now used to heat the wires?

W
