Overview

The Wheatstone bridge is a technique for measuring voltage or resistance changes. The voltage between the midpoints of two parallel voltage dividers is measured, and the value of one of the resistors in the bridge is adjusted to give a balance voltage of zero. Changes in the bridge voltage, resulting from a resistive transducer as one of the elements in the bridge, are then measured. If a parallel resistor is the bridge in part of the transducers, then temperature sensitivities are cancelled out. The Wheatstone bridge is well-suited for the measurement of small changes of a resistance.
