Question

In a potentiometer, a standard cell of emf 5V and of negligible resistance maintains a steady

current through the potentiometer wire of length 5m. Two primary cells of emf E1 and E2 are

joined in series with (i). Same polarity (ii). Opposite polarity. The combination is connected

through a galvanometer and a jockey to the potentiometer. The balancing lengths in the two

cases are found to be 350cm and 50 cm respectively.

(i). Draw the necessary circuit diagram

(ii). Find the value of the emf’s of the two cells.​
