Wheatstone Meter Bridge Diagram. The unknown resistance rx is to be measured. Defined simply a wheatstone bridge is an electric circuit that is used to measure the electrical resistance of a circuit.
The circuit is set out by balancing two legs of a bridge circuit. The device was first invented by samuel hunter christie in 1833. It can be used in all electronic circuits.
The concept was later modified and popularized by sir charles wheatstone in the year 1843.
