Definition of Wheatstone bridge in English:

Wheatstone bridge


  • A simple circuit for measuring an unknown resistance by connecting it so as to form a quadrilateral with three known resistances and applying a voltage between a pair of opposite corners.

    • ‘Because metal foil gauges are deposited onto their polyimide backing, they are often sold in prearranged Wheatstone bridges, rosettes, and other patterns.’
    • ‘From DC up to about 150 MHz Wheatstone bridges, or other bridges that are merely modified forms of a Wheatstone bridge, provide the most accurate method of measuring resistance or impedance.’
    • ‘Noise measurements of Wheatstone bridges made from spin valves with parallel and crossed anisotropies’
    • ‘He was advised and helped by his uncle Charles Wheatstone who invented the piece of electrical apparatus known as the Wheatstone bridge.’
    • ‘Leeds and Northrup of Philadelphia made an array of Wheatstone bridges, some with plugs and some, like this one, with dials and some plugs.’
    • ‘The Wheatstone bridge is unsuitable for measuring very small resistances, of a few ohms or less.’
    • ‘Scales using strain gages that I have observed have used Wheatstone bridges in structures differing from my structure.’
    • ‘The principle of measurement is similar to that of the Wheatstone bridge in electronics, in which an accurate measurement is made by comparing the unknown value against the value of a calibrated component.’
    • ‘This lesson describes Wheatstone bridges, megohmmeters, and clamp-on ammeters.’
    • ‘The Wheatstone bridge contains four resistances, a constant voltage input, and a voltage gage Wheatstone bridge circuit operation variations of the basic Wheatstone bridge circuit.’
    • ‘This procedure is for certification of five-dial Wheatstone bridges complete with maintenance procedures.’
    • ‘The Wheatstone bridge consists of four resistors connected together in a diamond orientation.’
    • ‘A Kelvin Double bridge is a variant of the Wheatstone bridge used for measuring very low resistances.’
    • ‘The Wheatstone bridge is an electrical circuit for the precise comparison of resistances.’
    • ‘This modified Wheatstone bridge is connected to a dual phase lock-in amplifier as shown above.’
    • ‘The Wheatstone bridge is balanced when there is no p.d. between the midpoints of the voltage dividers.’
    • ‘In using a Kelvin bridge, you must follow precautions similar to those given for the Wheatstone bridge.’
    • ‘When the Wheatstone bridge is balanced so that its two output points are equipotential, the unknown resistance can be determined by comparison with the three known resistances in the bridge.’
