Telephone companies make use of the Wheatstone bridge for _________.a...
Explanation:
Wheatstone Bridge:
- The Wheatstone bridge is a circuit used to measure an unknown electrical resistance by balancing two legs of a bridge circuit.
- It consists of four resistors, a voltage source, and a galvanometer.
Locating Cable Faults:
- Telephone companies use the Wheatstone bridge to locate faults in cables.
- When a fault occurs in a cable, it creates an imbalance in the resistance values in the circuit.
- By using the Wheatstone bridge, technicians can determine the exact location of the fault by measuring the resistance values on either side of the fault.
Working Principle:
- The Wheatstone bridge works on the principle of null detection, where the galvanometer reads zero when the bridge is balanced.
- If there is a fault in the cable, the resistance values change, causing the galvanometer to deflect from zero.
- By adjusting the known resistances in the bridge circuit, technicians can bring the bridge back into balance, indicating the location of the fault.
Benefits:
- Using the Wheatstone bridge for locating cable faults is a precise and efficient method.
- It helps in quickly identifying the exact location of the fault without the need for extensive manual testing.
- This method saves time and resources for telephone companies in maintaining and repairing their communication networks.
