NEET Physics Wheatstone Bridge MCQ Question
What is the condition for a Wheatstone bridge to achieve balance and provide zero deflection in the galvanometer?
R1/R2 = R3/R4
R1 + R2 = R3 + R4
R1 * R2 = R3 * R4
R1 - R2 = R3 - R4
Correct Answer
Detailed Explanation
The balance condition for a Wheatstone bridge states that the ratio of the resistances must be equal, specifically R1/R2 = R3/R4, which is derived from the conditions applied using Kirchhoff’s loop rule as described in the NCERT context.
