In an experiment to determine the emf E2 of an unknown cell, its emf i – InterviewSolution

1.	In an experiment to determine the emf E2 of an unknown cell, its emf is compared with a standard cell of known emf E1=1.12 V. The balance point is obtained at 56 cm with the standard cell and 80 cm with the unknown cell. Determine the emf of the unknown cell.
Answer» In an experiment to determine the emf $E_{2}$ of an unknown cell, its emf is compared with a standard cell of known emf $E_{1} = 1.12 V$ . The balance point is obtained at $56 cm$ with the standard cell and $80 cm$ with the unknown cell. Determine the emf of the unknown cell.
