Due to the Wheatstone bridge’s ability to measure very small changes in resistance, it is often used for measuring the strain on strain gauges. These detect changes in buildings, bridges and ...

A Wheatstone bridge is one of those handy circuits that has plenty of uses in both AC and DC measurements. We probably see them most often in a strain gauge.

Bridges are an integral part of measurement and measurement devices. Of the many DC bridges in existence, the Wheatstone bridge is the most often used. One use is to measure unknown resistance values.
