NEET Physics Wheatstone Bridge MCQ Question

Type: MCQ-fact-Hard-Class 12

What is the condition for a Wheatstone bridge to achieve balance and provide zero deflection in the galvanometer?

A

R1/R2 = R3/R4

B

R1 + R2 = R3 + R4

C

R1 * R2 = R3 * R4

D

R1 - R2 = R3 - R4

Correct Answer

Option A

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.
