BRIDGE CIRCUIT Meaning and
Definition
-
A bridge circuit is a type of electrical circuit commonly used in electronics and electrical engineering. It comprises a configuration of resistors or other components arranged in a bridge-like diagram. The primary purpose of a bridge circuit is to accurately measure an electrical quantity, such as voltage or resistance, by comparing it to a known or reference value.
The bridge circuit consists of four branches, with each branch containing a component. Two opposite branches typically consist of variable components, such as resistors or capacitors, while the remaining branches contain fixed components. The components are interconnected to form a closed loop.
When connected to a power source, a bridge circuit operates by balancing the variable components. By adjusting the variable components, the bridge circuit strives for a state of equilibrium where the voltage or resistance across the bridge becomes zero or equal to the reference value. This balanced state indicates that the unknown quantity being measured is equal to the reference value predetermined by the fixed components.
Bridge circuits offer high accuracy and precision in electrical measurements, as any small deviation from the balanced state can be easily detected. They are commonly used in various applications, including strain gauges, temperature sensors, and impedance measurements.

Etymology of BRIDGE CIRCUIT
The word "bridge" in the term "bridge circuit" comes from the literal meaning of a structure that connects two points or spans a gap. In the context of circuitry, a bridge circuit refers to a circuit configuration that is typically used to measure resistance or make precise measurements. The term "bridge circuit" has its origin in the concept of a physical bridge that connects two points. It references the idea that the circuit is dynamically balanced like a bridge, with several components working together to maintain equilibrium and provide accurate measurements.
