Question 12: NCERT Solutions for 12th Class Physics: Chapter 3-Current Electricity
In a potentiometer arrangement, a cell of emf 1.25 V gives a balance point at 35.0 cm length of the wire. If cell is replaced by another cell and the balance point shifts to 63.0 cm, what is the emf of the second cell?
Solution:
The potential gradient remains the same, as there is no change in the setting of standard circuit.
