IMPEDANCE BRIDGE Meaning and
Definition
-
An impedance bridge is a type of electrical measurement instrument used to accurately determine the impedance (or resistance and reactance) of a circuit or component. It operates on the principle of comparing an unknown impedance to a known reference impedance, allowing for precise measurement and analysis.
The bridge is typically composed of four arms, with one arm including the unknown impedance and the other arm containing a calibrated reference impedance. The remaining two arms consist of adjustable components, such as variable resistors or capacitors, which are adjusted until the bridge is in balance. At this point, there is no current flowing through the detector, and the bridge is said to be in a "null" state.
The impedance bridge functions by balancing the two sides of the circuit using AC or alternating current signals with a known frequency. By measuring the voltage and current at various points within the bridge circuit, the unknown impedance can be calculated using a mathematical formula.
This type of bridge provides accurate measurement of both resistance and reactance, making it valuable in a variety of applications including electronic circuit analysis, telecommunications, and electrical engineering research. Its precision and versatility enable impedance bridges to be widely used in industries where the measurement of impedance is crucial for the design, testing, and maintenance of electrical components and systems.

Etymology of IMPEDANCE BRIDGE
The word "impedance" is derived from the Latin word "impedire", meaning "to entangle" or "to hinder". It was first used in the late 19th century in the field of electrical engineering to describe a measure of opposition to the flow of alternating current in a circuit.
The term "bridge" in "impedance bridge" refers to the instrument used for measuring electrical impedance. A bridge circuit is a type of electrical circuit that is balanced, meaning the input and output voltages are equal. The use of a bridge circuit allows for accurate measurements of resistance, reactance, and impedance. Hence, the "impedance bridge" is a device designed to measure impedance accurately.
