In a wheatstone bridge if the battery and galvanometer are interchange...
Explanation:
In a Wheatstone bridge circuit, the resistance ratio is balanced to obtain a null deflection in the galvanometer. The balance condition is achieved when the ratio of the resistances in the two arms of the bridge is equal.
When the battery and galvanometer are interchanged, it means that the battery is connected to the galvanometer and the galvanometer is connected in place of the battery. This essentially means that the direction of current flow in the bridge circuit is reversed.
Reasoning:
When the direction of current flow in the bridge circuit is reversed, it does not affect the ratio of the resistances in the two arms of the bridge. Therefore, the balance condition remains the same.
The balance condition is defined as the condition where the potential difference across the galvanometer is zero. In other words, the current flowing through the galvanometer is zero and there is no deflection.
Since the balance condition remains the same even after interchanging the battery and galvanometer, the deflection in the galvanometer will not change. Therefore, the correct answer is option 'B' - the deflection in the galvanometer will not change.
Conclusion:
In a Wheatstone bridge circuit, when the battery and galvanometer are interchanged, the deflection in the galvanometer will not change. This is because the balance condition, which is based on the ratio of resistances in the two arms of the bridge, remains the same regardless of the direction of current flow.
