NEET 2026 Physics Metre Bridge MCQ Question
In a metre bridge experiment (see figure), the positions of the cell, E, and galvanometer, G, are interchanged. We shall observe in the galvanometer:
Only the left-sided deflection
There will be no deflection irrespective of the position of the jockey
Only the right-sided deflection
Both right-sided and left-sided deflection and at balance point, no deflection
Correct Answer
Detailed Explanation
Position of null point will not change when galvanometer (G) and the cell (E) are interchanged. There will be no deflection in galvanometer only at balance point. In an unbalanced meter bridge, if E and G are interchanged mutually, then the deflection in galvanometer may be towards left-side or right-side.
