`AB` is a potentiometer wire Fig. If the value of `R` is increased, in which direction will the balance point `J` shift ?
Text Solution
Verified by Experts
If `R` is incresed, the current through the potentiometer wire will decrease. Due to it, the potential gradient of potentiometer wire will also decrease. As a result of it. The balancing length will increase, i.e., the position of `J` will shift on potentiometer wire towards `B`.
