| ASSERTION: A larger dry cell has higher emf. |
| REASON: The emf of a dry cell is proportional to its size. |
A) If both assertion and reason are true and reason is the correct explanation of assertion.
B) If both assertion and reason are true and reason is not the correct explanation of assertion.
C) If assertion is true but reason is false.
D) If both assertion and reason are false.
E) If assertion is false but reason is true.
Correct Answer: D
Solution :
The electrical force of a cell or battery called electromotive force (e.m.f.) This force, which makes electrons flow around a circuit. Each kind of cell has a particular e.m.f. The size of a cell has no effect of its emf. The chemicals ion the cell determines its emf. But large cells last longer than small cells of same basic type. This means that from a large cell, we get particular emf for more time as compared to small cell.
