Introduction:
Solving numerical problems is an essential part of electrical engineering practice as it helps in developing problem-solving skills and understanding the concepts in a practical manner. However, the use of calculators while solving these problems is a topic of debate. Let us explore the advantages and disadvantages of solving numerical problems with and without the use of calculators.

Solving numerical problems with calculators:
Using calculators while solving numerical problems in electrical engineering practice has its advantages:

- Time-saving: Calculators can perform complex calculations quickly, saving a significant amount of time during problem-solving. This allows engineers to focus on understanding the concepts and analyzing the results rather than spending time on manual calculations.

- Reduced chances of errors: Calculators eliminate the risk of manual calculation errors, which can be common in complex calculations. This ensures accurate results and prevents potential mistakes that could lead to incorrect solutions.

- Real-world applications: In real-world scenarios, engineers often use calculators during their work to perform calculations efficiently. Therefore, practicing with calculators can help individuals become familiar with the tools they will use in their professional careers.

Solving numerical problems without calculators:
While using calculators has its advantages, there are also benefits to solving numerical problems without relying on calculators:

- Enhanced understanding of concepts: Solving problems manually helps in developing a deeper understanding of the underlying concepts and principles. By performing calculations step-by-step, engineers can grasp the intricacies of the problem and gain insights into the principles involved.

- Improved problem-solving skills: Manual calculations require logical thinking and problem-solving skills. By solving problems without calculators, engineers can enhance their ability to break down complex problems, identify the relevant equations, and apply appropriate techniques to arrive at the solutions.

- Flexibility in different scenarios: In some situations, calculators may not be readily available or practical to use. By practicing manual calculations, engineers become more adaptable and can solve problems even in situations where calculators are not accessible.

Conclusion:
In conclusion, both solving numerical problems with and without calculators have their merits. While calculators offer time-saving benefits and reduce the chances of errors, solving problems manually enhances the understanding of concepts and improves problem-solving skills. Therefore, it is recommended to strike a balance between the two approaches. Initially, engineers can solve problems manually to solidify their understanding and develop problem-solving skills. Subsequently, they can also use calculators to improve efficiency and accuracy. By combining both approaches, engineers can develop a well-rounded skillset that prepares them for the challenges of electrical engineering practice.
