Bridge Circuits for Precision Measurement Quiz…

Q: Which of the following is the most common type of bridge circuit?

Wheatstone Bridge — Wheatstone bridge is widely used for measuring resistance.

Q: What is the primary purpose of a bridge circuit in measurement applications?

To measure impedance — Bridge circuits are primarily used to accurately measure impedance, including resistance, inductance, and capacitance.

Q: In a balanced Wheatstone bridge, the current through the detector is:

Zero — A balanced bridge has no potential difference across the detector, resulting in zero current.

Q: Which component is typically used as a null detector in a bridge circuit?

Galvanometer — A galvanometer is a sensitive instrument used to detect small currents, indicating a balanced condition.

Q: What type of component is often measured using a Maxwell bridge?

Inductors — The Maxwell bridge is specifically designed for measuring inductance.

Q: The accuracy of a bridge circuit measurement depends on:

The precision of the known components — Accurate known components are crucial for precise measurement.

Q: Which bridge circuit is used for the measurement of capacitance?

Schering bridge — Schering bridge is specifically designed to measure capacitance.

Q: What is a major advantage of using bridge circuits for measurement?

They provide very accurate measurements. — Bridge circuits are known for providing highly accurate measurements because the balance condition is independent of the source voltage.

Q: In a bridge circuit, how is the unknown impedance determined?

By comparing it with a known impedance. — The unknown impedance is determined by comparing its value to known components at balance.

Q: A Wien bridge is commonly used for:

Measuring capacitance and frequency. — The Wien bridge is used to measure capacitance and also to measure frequency.
