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.
