## Homework Statement

A 10-km-long underground cable extends east to west and

consists of two parallel wires, each of which has resistance 13 ohm /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 ohm when measured from

the east end and 200 ohm when measured

from the west end. What are

(a) x and (b) R?

## Homework Equations

## The Attempt at a Solution

Actually I don't know how to start this problem, should the total resistance of wire and R get added up?
