Question

Capacitance can be measured using

• A. Maxwell's bridge
• B. Schering's bridge
• C. Campbell bridge
• D. Wien's bridge

Hint:

AC Bridges. Maxwell (Inductance L), Hay (High Q Inductance L), Schering (Capacitance C, dissipation factor D), Campbell (Mutual Inductance M), Wien (Frequency f).

Answer 1

The Correct Option is B

Different AC bridge circuits are designed for measuring specific electrical quantities: - Maxwell's bridge: Used primarily for measuring unknown inductance (typically medium Q coils) in terms of a standard capacitance
- Schering's bridge: Widely used for measuring unknown capacitance, especially for determining the capacitance and dissipation factor (or loss angle) of capacitors and insulating materials, including high voltage applications
- Campbell bridge: Used for measuring mutual inductance
- Wien's bridge: Primarily used for measuring frequency, although it can be adapted for capacitance measurement, it's less common for general capacitance measurement than Schering bridge
Therefore, the Schering bridge is the standard AC bridge circuit specifically designed for capacitance measurements
