    Description

    Antique Wheatstone Bridge Slide Wire Rare
    The
    Wheatstone Bridge
    was originally developed by Charles Wheatstone to measure unknown resistance values and as a means of calibrating measuring instruments, voltmeters, ammeters, etc, by the use of a long resistive slide wire.
    Although today digital multimeters provide the simplest way to measure a resistance. The
    Wheatstone Bridge
    can still be used to measure very low values of resistances down in the milli-Ohms range.
    The Wheatstone bridge (or resistance bridge) circuit can be used in a number of applications and today, with modern operational amplifiers we can use the
    Wheatstone Bridge Circuit
    to interface various transducers and sensors to these amplifier circuits.
    The Wheatstone Bridge circuit is nothing more than two simple series-parallel arrangements of resistances connected between a voltage supply terminal and ground producing zero voltage difference between the two parallel branches when balanced. A Wheatstone bridge circuit has two input terminals and two output terminals consisting of four resistors configured in a diamond-like arrangement as shown. This is typical of how the Wheatstone bridge is drawn.
    An electrical measuring device, likely a slide-wire Wheatstone bridge.  This example is comprised of a oak board with a slide wire ruler at the bottom
