AB is a potentiometer wire. If the value of R is increased, then in which direction will the balance point shift? |
Towards A Towards B No change Will remain fixed at the mid of wire AB |
Towards B |
The correct answer is Option (2) → Towards B As the resistance is increased, the value of potential gradient decreases. Hence to balance the cell now the balance point would shift towards B as larger resistance of potentiometer wire would be needed to obtain balance point. |
