### What is Meant by the Wheatstone Bridge?

In Physics, the Wheatstone bridge is also known as the resistance bridge. The Wheatstone bridge consists of four arms. The two arms consist of known resistance, and the other two arms consist of variable resistance and unknown resistance. The Wheatstone bridge consists of an electromotive force and a galvanometer. It works on the principle of null deflection. The bridge is considered to be in a balanced condition when no current flows through the galvanometer. Generally, this condition is achieved by adjusting the known and the variable resistance. The formula to calculate the bridge voltage is given as:

$$\begin{array}{l}v_{b}= v_{in}\ast (\frac{R_{x}}{R_{x}+R_{c}}-\frac{R_{b}}{R_{b}+R_{a}})\end{array}$$

Where

Vin is the input voltage

Vb is the bridge voltage

Ra, Rb, Rc, Rx are the resistance.
