A bridge circuit is a special type of electrical circuit wherein the current from a voltage source splits into two parallel paths.

These parallel paths contain components (such as resistors, capacitors, and inductors) the types and arrangement of which depend on what the purpose of the bridge circuit is.

The parallel paths recombine again to let the current return to the source in a single conductor, thereby closing the circuit.

The parallel paths are 'bridged' together by another electrical path that usually contains a load or a measuring device (such as a galvanometer), hence the name 'bridge circuit.'

Bridge circuits are primarily used in measurement applications and power supplies.

There are many bridge circuits, the more widely known of which are as follows:

1) Wien Bridge
2) Schering Bridge
3) Hay Bridge
4) Owen Bridge
5) Maxwell Bridge
6) Resonance Bridge
7) Wheatstone Bridge
