Solution
An unbalanced Wheatstone bridge indicates an imbalance in the network because the galvanometer shows non-zero deflection. This deflection signals that the potential difference between the two galvanometer junctions is not zero, meaning the ratio of resistances does not satisfy the balance condition.
