NEET Physics Wheatstone Bridge Assertion Reason Question
Assertion (A): In a balanced Wheatstone bridge, the galvanometer shows zero deflection. | Reason (R): The balance condition for the bridge is R1/R2 = R3/R4.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
The balance condition of R1/R2 = R3/R4 ensures the galvanometer shows zero deflection, as per the Wheatstone bridge context in the NCERT.
