Q. No.Given below are two statements:
Assertion (A):
In the Wheatstone Bridge shown in the figure, if the resistances in opposite arms are switched (i.e. \(Q, R \) are exchanged) then the bridge remains balanced if it was initially balanced.
Reason (R):
The balance condition \(\dfrac P Q\) = \(\dfrac R S\) is not affected if resistances in opposite arms are switched.
1.
(A) is True but (R) is False.
2.
(A) is False but (R) is True.
3.
Both (A) and (R) are True and (R) is the correct explanation of (A).
4.
Both (A) and (R) are True but (R) is not the correct explanation of (A).
