उत्तर
Assertion (A) is true and Reason (R) is false.
Explanation:
For a balanced Wheatstone Bridge,
`P/Q = R/S`
⇒ `2/3 = 3/2`
0.67 = 1.5
`P/Q ≠ R/S`
As a result, it isn't a balanced Wheatstone bridge. The current through a galvanometer must be zero in the case of a balanced Wheatstone bridge. As a result, the reason is incorrect and the statement is correct.
