Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDF- A Wheatstone bridge is a special arrangement of 4 resistors. It can be used to find an unknown resistance.
- If the Wheatstone bridge is balanced, there will be no current flowing through the galvanometer.
- Wheatstone bridge is used to measure the resistance with the help of a comparison method.
- The Wheatstone bridge work on the principle of null deflection.
The bridge is balanced when:
\(\frac{P}{R}=\frac{Q}{S}\)
∴ A Wheatstone bridge is balanced if the ratio of resistors on one side of the bridge equals to the ratio of resistors on the other side.
