Chapter , Problem 13(choose chapter or problem)
A 10-km-long underground cable extends east to west and consists of two parallel wires, each of which has resistance 13 /km. An electrical short develops at distance x from the west end when a conducting path of resistance R connects the wires (Fig. 27-31). The resistance of the wires and the short is then 100 0 when measured from the east end and 200 0 when measured from the west end. What are (a) x and (b) R? West East Conducting path x Figure 27-31 13.
