In the potentiome

Answer :

(a) As the resistance R increases, the current through the wire decreases. Hence, the potential difference across AX will also decrease. To counter it, the resistance will have to increase and the null point will shift towards B.

(b) Here, the terminal potential difference decreases as S increases. Hence, the balance point will shift towards A.
