NEET Physics Wheatstone Bridge Assertion Reason Question
Assertion (A): In a balanced Wheatstone bridge, the current through the galvanometer is zero. | Reason (R): The balance condition for a Wheatstone bridge is given by R1/R2 = R3/R4, where R1, R2, R3, and R4 are the resistances in the bridge.
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
In a balanced Wheatstone bridge, the condition R1/R2 = R3/R4 ensures that there is no potential difference across the galvanometer, resulting in zero current.
