In a potentiometer experiment, for measuring internal resistance of a cell, the balance point has been obtained on the fourth wire. The balance point can be shifted to fifth wire by
- a)increasing the current due to auxiliary battery
- b)Putting a shunt resistance in parallel with the cell.
- c)decreasing the current due to auxiliary battery
- d)putting a suitable resistance in series with the cell.
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
In a potentiometer experiment, for measuring internal resistance of a ...
Explanation:If the current due to the auxillary battery is decreased, the potential gradient will be decreases, so the balancing length increases.Thus null point will move to fifth wire.

In a potentiometer experiment, for measuring internal resistance of a ...
Explanation:
Decreasing the current due to the auxiliary battery:
- The balance point in a potentiometer experiment is obtained when the potential difference across the cell equals the potential difference across the potentiometer wire.
- By decreasing the current due to the auxiliary battery, the potential difference across the cell decreases, causing the balance point to shift to a higher resistance wire (in this case, the fifth wire).
- This shift occurs because the potential difference across the potentiometer wire remains constant, while the potential difference across the cell decreases.
- Therefore, option 'C' is the correct answer as it explains how the balance point can be shifted to the fifth wire by decreasing the current due to the auxiliary battery.
