What is the primary function of an LCR meter in electronics?

An LCR meter is specifically designed to measure inductance, capacitance, and resistance. These components are fundamental to many electronic circuits, and accurately determining their values is crucial for troubleshooting, design verification, and ensuring the proper functioning of electronic devices.

Inductance is measured by subjecting coils or inductors to an alternating current, while capacitance is determined by assessing capacitors in similar conditions. Resistance measurement is performed by applying a small known voltage and measuring the resulting current. This ability to quantify these three parameters makes the LCR meter an essential tool for electricians and engineers working with various electronic components, allowing them to make informed decisions on repairs, replacements, or designing new circuits.

The other options do not reflect the primary functions of the LCR meter. For instance, measuring voltage and current pertains more to a multimeter, while waveform distortion analysis typically involves oscilloscopes or signal analyzers. Power supply feedback is related to controlling and regulating power supplies rather than component measurement.
