Question

Which one of the following bridges CANNOT be used for measuring inductance?

• A. Schering Bridge
• B. Maxwell Wien Bridge
• C. Hay Bridge
• D. Series Owen Bridge

Hint:

- Schering Bridge → Capacitance measurement.
- Maxwell, Hay, Owen Bridges → Inductance measurement.

Answer 1

The Correct Option is A

Step 1: Schering Bridge is primarily used for measuring the capacitance, dielectric loss, and power factor of a capacitor. It is not used for measuring inductance.
Step 2: Maxwell Wien Bridge is used for the measurement of self-inductance in terms of a known capacitance.
Step 3: Hay Bridge is also used for measuring inductance, particularly for coils with high Q-factors.
Step 4: Series Owen Bridge is used for the measurement of inductance over a wide range of values.
Step 5: Hence, the bridge that cannot be used for inductance measurement is the Schering Bridge.
