To make an AC bridge balance, two conditions must be satisfied: the impedance of the two branches of the bridge must be equal, and the phase difference between the two branches must be zero. This means that the voltage across the two opposing points of the bridge must be equal in both magnitude and phase. When these conditions are met, no current flows through the galvanometer connected between the two points, indicating a balanced bridge.
