170 kW (1.7 105 W) of power is delivered to the other side of a city by a pair of power lines between which the voltage is 10000 V.
(a) What current flows in the lines?
___A
(b) Each of the two lines has a resistance of 5 ohms. What is the voltage change along each line? (Think carefully. This voltage change is along each line, not between the lines.)
___V
(c) What power is expended as heat in both lines together (distinct from power delivered to customers)?
___kW
PLEASE EXPLAIN ANSWERS!
THANK YOU SO MUCH IN ADVANCE!
