AB is a wire of potentiometer with the increase in the value of resistance R, the shift in the balance point J will be
A
Towards B
B
Towards A
C
Remains constant
D
First towards B then back towards A.
Answer
Towards B
Explanation
Solution
: Due to increase in resistance R the current through the wire will decrease and hence the potential gradient also decreases, which results in increase in balancing length. So J will shift towards B.
