Measurement Of R L C Using Bridge Circuits in Electrical And Electronics Measurements : Practice MCQ Questions & Answers with Explanations

Explanation: Maxwell Inductance Capacitance Bridge (Maxwell Bridge): Definition: A Maxwell Inductance Capacitance Bridge, commonly referred to as a Maxwell Bridge, is a modified version of the Wheatstone bridge used for precise measurement of the self-inductance of a circuit. It operates on the principle of balancing the bridge circuit to determine unknown inductances by comparing them with known capacitances and resistances. Working Principle: The Maxwell Bridge functions by using the balancing condition of an AC bridge.

Explanation: Current Transformers Definition: Current transformers (CTs) are devices used in electrical engineering to transform high voltage currents into lower, manageable currents for measurement and monitoring purposes. They are specifically designed to provide a scaled-down representation of the current flowing in a power system, making it safe and convenient to monitor high voltage circuits using standard measuring instruments like ammeters. Working Principle: Current transformers operate on the principle of electromagnetic induction.
