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...
The Wheatstone Bridge is used for measuring the very low resistance values precisely.Wheatstone bridge along with operational amplifier is used to measure the physical parameters like temperature, strain, light, etc.We can also measure the quantities capacitance, inductance and impedance using the variations on the Wheatstone Bridge.A beginner’s guide on Wheatstone Bridge. You learned What is a Wheatstone Bridge Circuit, what is the meaning of a Balanced Bridge, how to calculate an unknown resistance using Wheatstone Bridge and also how an Unbalanced Wheatstone Bridge can be used to measure different physical quantities like Temperature and Strain.
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, RX due, for example, to changes in light intensity as we have seen above.
The Wheatstone bridge illustrates the concept of a difference measurement, which can be extremely accurate. Variations on the Wheatstone bridge can be used to measure capacitance, inductance, impedance and other quantities, such as the amount of combustible gases in a sample, with an explosimeter.
Oct 26, 2023 · Conclusion. In conclusion, the Wheatstone Bridge is a fundamental tool in the electrical engineering world due to its ability to measure unknown resistances with remarkable accuracy. Its simplicity, combined with its precision and versatility, have ensured its continued relevance over the years.
The Wheatstone bridge can be used to compare the value of two resistances – or, if the unknown resistance is compared with a resistance whose value is known, it can be used to measure an unknown resistance. R1 and R2 can be varied. R3 is a standard resistance whose value is known.
Wheatstone bridges are commonly used to measure the resistance of a few ohms to those few kilo-ohms. If the four resistances are not equivalent, the circuit’s sensitivity is reduced. Conclusion. Thus, Wheatstone Bridge is a device used to measure the unknown resistance of a resistor when the other resistance is known.
