AB is wire of potentiometer with the increase in the value of resistance R, the shift in the balance point J will be

A

toward B

B

toward A

C

remains constant

D

first towards B then back towards A

Text Solution

Verified by Experts

The correct Answer is:
A
Due to increase in resistance R the current through the wire will decrease and hence the potentail gradient also decreases, which results in increase in balancing length. So J will shift towards B.
