Applications of weidstone bridge??

Answer 1

Meter bridge, post office

box and Carey Foster bridge are instruments based on the principle of

wheatstone bridge and are used to measure unknown resistance.

Answer 2

The term Wheatstone bridge is invented and named by Charles Wheatstone. The main purpose of this circuit is to calculate the value of unknown resistance. But, the current digital multimeters gives a simple way to calculate a resistance. The applications of the Wheatstone bridge mainly involves, it can be used in amplifier circuits to interface different sensors and transducers with modern operational amplifiers. The Wheatstone bridge circuit is designed with two serial and parallel resistances in between two terminals like voltage and ground. When the Wheatstone bridge is stable, then the GND terminal creates a zero voltage difference b/n the two parallel branches. A Wheatstone bridge circuit comprises of two i/p terminals and two o/p terminals, that are arranged in a diamond shape using four transistors
