The energy given by the cell in the flow of unit charge in the whole circuit is called the emf of the cell. The emf is a characteristic of the cell which depends upon the nature of the plates and the electrolyte used in cell. Hence, the emf does not depend upon the size of the cell.

Assertion : A larger dry cell has higher emf.
Reason : The emf of a dry cell is proportional to its size.
The correct answer to this question is option 'D', which states that both the Assertion and Reason are incorrect. Let's analyze why this is the case.
Explanation:
1. Understanding the Assertion:
- The Assertion states that a larger dry cell has a higher emf.
- Emf stands for electromotive force, which is the potential difference or voltage produced by a source of electrical energy, such as a battery or cell.
- The Assertion implies that the size of a dry cell directly influences its emf.
2. Evaluating the Reason:
- The Reason provided for the Assertion is that the emf of a dry cell is proportional to its size.
- Proportional means that as one variable increases, the other variable also increases in direct proportion.
- In this case, the Reason suggests that as the size of a dry cell increases, its emf also increases.
3. Analyzing the Assertion and Reason:
- The Assertion and Reason both state that the size of a dry cell is related to its emf.
- However, this relationship between size and emf is not accurate or supported by scientific principles.
- The emf of a dry cell is primarily determined by the chemical reactions occurring within the cell, not its physical size.
- The size of a dry cell may affect its capacity to store energy or the duration of its performance, but it does not directly impact the emf.
4. Conclusion:
- Based on the analysis, it is evident that both the Assertion and Reason are incorrect.
- A larger dry cell does not necessarily have a higher emf, and the emf of a dry cell is not directly proportional to its size.
- The correct answer is option 'D' - both the Assertion and Reason are incorrect.
In summary, it is important to critically evaluate the statements provided in the question and analyze whether they align with scientific principles. In this case, the relationship between the size of a dry cell and its emf is not accurate, leading to the conclusion that both the Assertion and Reason are incorrect.
