Telephone companies make use of the Wheatstone bridge for _________(a)

1.	Telephone companies make use of the Wheatstone bridge for _________(a) measuring the telephone resistance(b) computing the line strength(c) maintaining dialtone(d) locating the cable faultsI have been asked this question during an online exam.This question is from Applications of Wheatstone Bridge in portion Measurement of Resistance of Electrical Measurements
Answer» The CORRECT choice is (d) locating the cable faults Easy explanation: Cable faults in telephones can be located by telephone companies by MAKING use of a Wheatstone BRIDGE. TELEPHONIC resistances are determined using suitable techniques. Dialtone is maintained through optical fibre technology.
