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 - R3 = R2 - R4
R1 * R4 = R2 * R3
Correct Answer
Detailed Explanation
The balance condition for a Wheatstone Bridge is given by the equation R1/R2 = R3/R4, which ensures that there is no current flowing through the galvanometer, leading to a null deflection.
