What are the Applications and Limitations of Wheatstone Bridge?

In order to find an unknown resistance in a circuit, the Wheatstone bridge is actively used. And it is very important to solve various types of problems and questions that involve resistors, and other circuits. So, it is very important for the students to understand the working of Wheatstone Bridge. And therefore, to help you out, here in the article below, we will provide a comprehensive description of Wheatstone Bridge.

Principle of Wheatstone Bridge
The Basic Principle of Wheatstone Bridge is the Principle of Null Deflection. According to this principle, there is no current present in this circuit, and the ratio of resistances is said to be the same. Moreover, at first, the bridge in the circuit, as shown in the diagram, exists in an unbalanced condition, and they can find the current is indeed flowing through the galvanometer. However, in order to keep the bridge in a balanced condition, there should not be any current flow in the circuit. Although to achieve this balanced position, it is needed to adjust the variable resistance and known resistance in the circuit.

Construction of Wheatstone Bridge
The Wheatstone Bridge consists of four arms, two known and two unknown resistances, and more importantly a variable resistance. The G symbol located in the center of the circuit represents Galvanometer. And the emf source is attached to points a and c, while the galvanometer is connected between points b and d.

Applications of Wheatstone Bridge
In order to measure the low resistance in a circuit.
Other important quantities such as Capacitance, Impedance, and Inductance, can also be calculated using Wheatstone Bridge.
By using an optional amplifier, in the Wheatstone bridge, we will be able to measure physical parameters like Strain, Light, and Temperature.
Limitations of Wheatstone Bridge
There are certain limitations to all types of principles in Physics, including the Wheatstone Bridge.

Excessive current flow in the Wheatstone Bridge may result in a permanent change in the value of resistance.
When low resistance is applied, leads and contacts in the circuit will cause an error, and their values will attain constant.
And in terms of high resistance, the measured values are off-charts, then the galvanometer is considered to be in imbalance.
There are many other complex topics and chapters in Physics subject, which might need the students to put in some extra hard work to understand them easily and thoroughly. However, instead of self-study, we suggest students join online interactive classes. And if you are looking for a cost-effective online coaching program, with amazing benefits, then go check out the online interactive class programs offered by the Tutoroot platform.
