Textbook Question
Chapter 9, Problem 44TAS
A power of 100 kW (105W) is delivered to the other side of a city by a pair of power lines, between which the voltage is 12,000 V.
(a) Use the formula P = IV to show that the current in the lines is 8.3 A.
(b) Show that if each of the two lines has a resistance of 10 Ω, there is a 83-V change of voltage along each line, (Think carefully. This voltage change is along each line, set between the lines.)
