In a potentiometre, the balanced point is obtained when:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → the potential difference of the wire between the +ve end and the jockey becomes equal to the emf of the experimental cell
The balanced point is obtained when the potential difference of the wire between the positive end and the jockey because equal to the emf of the experiment cell and such that no current flow in the galvanometer.
