Introduction:
In the field of Electrical Engineering, equations and formulas play a crucial role in understanding and solving complex problems. Including equations and formulas in the answers of the Electrical Engineering optional subject can greatly enhance the clarity and precision of the response. Here are the reasons why it is better to include equations and formulas in the answers:

1. Precise and Accurate Representation:
Equations and formulas provide a precise and accurate representation of the concepts and principles in Electrical Engineering. They allow for a concise expression of relationships between different variables, making it easier to convey ideas and solutions effectively.

2. Clear Communication:
Including equations and formulas in the answers helps in clear communication of ideas and concepts. They provide a common language that is universally understood by professionals in the field. By using equations, the answer can be articulated in a more structured and organized manner, reducing the chances of misinterpretation.

3. Comprehensive Understanding:
Equations and formulas are the backbone of Electrical Engineering. By including them in the answers, it demonstrates a comprehensive understanding of the subject matter. It shows that the candidate not only knows the theoretical concepts but also possesses the ability to apply them to solve real-world problems.

4. Problem-Solving Efficiency:
Equations and formulas provide a systematic approach to problem-solving. By including them in the answers, the candidate can showcase their ability to break down complex problems into simpler equations or formulas, making the solution process more efficient and effective.

5. Standardization:
Equations and formulas are a standardized way of representing electrical concepts and principles. By including them in the answers, it ensures consistency and conformity to established practices in the field. This allows for easy comparison and evaluation of the candidate's response by the examiners.

Conclusion:
Including equations and formulas in the answers of the Electrical Engineering optional subject is highly recommended. It helps in precise representation, clear communication, comprehensive understanding, efficient problem-solving, and standardization. By doing so, candidates can enhance the quality and effectiveness of their responses, thereby increasing their chances of success in the UPSC examination.
