A generating station is producing 17 x 106 w of power that, Ask an Expert

Academics

A generating station is producing 1.7 x 106 W of power that is to be sent to a small town located 4.2 km away. Each of the two wires that comprise the transmission line has a resistance per length of 3.4 x 10-2/km. (a) Find the power lost in heating the wires if the power is transmitted at 1800 V. (b) A 100:1 step-up transformer is used to raise the voltage before the power is transmitted. How much power is now lost in heating the wires?
