MHT CET Physics question

In a Wheatstone’s bridge, the positions of the battery and the galvanometer are interchanged. In this case the balance condition.

(A)Changes
(B)Does not changeCorrect
(C)Is not applicable as it is not acting as a Wheatstone’s bridge
(D)Will depend upon the relaive magnitudes of the internal resistance of the battery and the resistance of the galvanometer.

Answer: (B)

Solution

The balance condition P/Q = R/S is symmetric in the conjugate arms, so the bridge stays balanced when the battery and the galvanometer are
