When we talk of a Wheat Stone Bridge, we say that if the two pairs of resistances in the top row, and the two in the bottom row have the same ratio of the value of their resistances, then no current flows through the connecting wire in the middle. But, that applies if the current is entering from one junction, and leaving the other. What happens, if the electric field in the wires (battery) originates from someplace else, like the original position of the galvanometer? And the galvanometer is placed where the battery was in the original circuit? Will the galvanometer show any deflection?
