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?
