NEET Physics Wheatstone Bridge Assertion Reason Question
Assertion (A): In a balanced Wheatstone bridge, the ratio of the resistances in one pair of opposite arms is equal to the ratio in the other pair. | Reason (R): The balance condition for a Wheatstone bridge is derived using Kirchhoff's loop rule.
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 but R is true.
Correct Answer
Detailed Explanation
A balanced Wheatstone bridge satisfies the condition R1/R2 = R3/R4, which is derived using Kirchhoff's loop rule, making R the correct explanation of A.
