Definitions from the WebBridge CircuitDefinition:A bridge circuit refers to a type of electrical circuit that is constructed using four resistive elements or components, typically arranged in a diamond-shaped configuration. It is used to measure resistance, detect changes in resistance, or balance two legs of a circuit. Usage:1. Sense of measurement: A bridge circuit is commonly used in electrical and electronic engineering for measuring unknown resistance values. It provides an effective means to determine the resistance through a comparison of known values in a balanced circuit. Example: To calculate the resistance of an unknown resistor, we can connect it to a bridge circuit and adjust the other resistors until the circuit becomes balanced. 2. Sense of detection: In certain applications, a bridge circuit can be employed to detect changes in resistance. It is particularly useful in applications where even minimal resistance variations need to be precisely measured. Example: A bridge circuit can be used in strain gauges to detect minute changes in mechanical strain by measuring the corresponding resistance alterations. 3. Sense of balance: The bridge circuit finds its application in balancing two-sided circuits, ensuring that both sides offer equal resistance and eliminate any undesired voltage variations. Example: In audio applications, a bridge circuit can be used to achieve impedance matching, ensuring that the load presented to a speaker is balanced and results in optimal sound quality.
