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, 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. Enroll now at Tutoroot.
