BALANCED WHEATSTONE BRIDGE

Figure shows a balanced Wheatstone's bridge (1) If P is slightly increased, the current in the galvanometer flow from A to C. (2) If P is slightly increased, the current in the galvanometer flows C to A. (3) If Q is slightly increased, the current in the galvanometer flows from C to A. (4) If Q is slightly increased, the current in the galvanometer flows from A to C.

Statement I : If the resistance of the first two arms P and Q of a balanced Wheatstone bridge are exchanged , the balanced condition is not disturbed . Statement II : The balanced condition of a Wheatstone bridge is independent of the resistance of the galvanometer used .

State whether the following statements are True (T) or False (F): The balance condition in Wheatstone's bridge circuit can not be obtained applying Ohms law only.

In the case of Wheatstone's Bridge, the bridge balance condition will be obtained only when ______

In a balanced Wheatstone's bridge, if the position of the galvanometer and cell is interchanged then the balanced condition will
