The Wheatstone Bridge has many uses in electronic circuits other than comparing an unknown resistance with a known resistance. When used with Operational Amplifiers, the Wheatstone bridge circuit can be used to measure and amplify small changes in resistance, R X due, for example, to changes in light intensity as we have seen above.

In the World of analog electronics, we come across various signals, some of them are measured by changes in resistance and some of them are with changes in inductance and capacitance. If we consider the resistance, most of the industrial sensors like temperature, strain, humidity, displacement, liquid level, etc. produces the change in value of the...
Bridge Networks or Circuits are one of the most popular and popular electrical tools, often used in measurement circuits, transducer circuits, switching circuits and also in oscillators. The Wheatstone Bridge is one of the most common and simplest bridge network / circuit, which can be used to measure resistance very precisely. But often the Wheats...
If VOUT in the above circuit is not equal to 0 (VOUT≠ 0), the Wheatstone is said to be an Unbalanced Wheatstone Bridge. Usually, the Unbalanced Wheatstone Bridge is often used for measurement of different physical quantities like Pressure, Temperature, Strain etc. For this to work, the Transducermust be of resistive type i.e., the resistance of the...
