NEET Physics Wheatstone Bridge MCQ Question
What condition must be satisfied for a Wheatstone bridge to achieve a null deflection in the galvanometer?
R1/R2 = R3/R4
R1 + R2 = R3 + R4
R1 - R2 = R3 - R4
R1 * R3 = R2 * R4
Correct Answer
Detailed Explanation
The balance condition for the Wheatstone bridge states that the ratio of resistances must be equal for the bridge to give a null deflection, specifically R1/R2 = R3/R4.
