An AC bridge, two arms of which are two serially connected tightly coupled inductive coils. The point of connection of these coils is usually grounded, and the coupling is arranged in such a way that for the currents simultaneously entering or leaving the other ends of the coils the voltage drop between the ends is close to zero. If one of the currents is entering and another is leaving, then the voltage drop is essential. This creates a sensitive current-comparing bridge having application in capacitance transducers.

the ration of the transformers arms can be quoted to a much higher accuracy than the ration of bridge equipment.
