Right Answer is:

All of the above

SOLUTION

Applications of Wheatstone Bridge

1. The Wheatstone bridge is basically a d.c. bridge and used to measure the medium resistance in the range 1Ω to low megaohm.

2. It is used to measure the D.C. resistance of various types of wire either for the purpose of quality control of the wire itself or of some assembly in which it is used.

3. It is used by telephone companies to locate cable faults. The fault may be two lines shorted together, or a single line shorted to the ground. If there is a fault on the cables, the Wheatstone bridge can be used to find the location of the fault by using the known resistance per meter of the cables.

4. It is used for the Measurement of the resistance of motor windings, transformers, solenoids, and relay coils.
