A bridge circuit is a topology of electrical circuitry in which two circuit branches (usually in parallel with each other) are “bridged” by a third branch connected between the first two branches at some intermediate point along them. The bridge was originally developed for laboratory measurement purposes and one of the intermediate bridging points is often adjustable when so used. Bridge circuits now find many applications, both linear and non-linear, including in instrumentation, filtering and power conversion.
