Chapter 9, Problem 44(choose chapter or problem)
A power of 100 kW (105 W) is delivered to the other sideof a city by a pair of power lines, between which the voltageis 12,000 V.(a) Use the formula P = IV to show that the current inthe lines is 8.3 A.(b) If each of the two lines has a resistance of 10 ,show that there is a 83-V change of voltage along eachline. (Think carefully. This voltage change is along eachline, not between the lines.) (c) Show that the power expended as heat in both linestogether is 1.38 kW (distinct from power delivered tocustomers).(d) How do your calculations support the importance ofstepping voltages up with transformers for long-distancetransmission?
