A Wheatstone bridge is a measuring instrument invented by Samuel Hunter Christie in 1833 and improved and popularized by Sir Charles Wheatstone in 1843. It is used to measure an unknown electrical resistance by balancing two legs of a bridge circuit, one leg of which includes the unknown component. Its operation is similar to the original potentiometer except that in potentiometer circuits the meter used is a sensitive galvanometer.

A bridge circuit in electronics is two series components connected in parallel with two other series components.
The path from the center point of one series pair to the center point of the other series pair is considered the center of the bridge.
Current that flows through a fifth component connected to these two bridge points is the focus of attention in a bridge circuit.
Large changes in current through the center of the bridge easily expose minute changes in the components of the two series pairs.
