Question

Figure (a) below shows a Wheatstone bridge in which P, Q, R, S are fixed resistances, G is a galvanometer and B is a battery. For this particular case the galvanometer shows zero deflection. Now, only the positions of B and G are interchanged,. as shown in figure (b). The new deflection of the galvanometer

is to the left.

Solution

The correct option is C is zero.
Since, $i_{g} = 0$
Still it will be a balanced W.S.B.
So, again $i_{g} = 0$
