Analysis of BARC EE 2020 Paper: A Comprehensive Guide for Aspirants

Introduction

The Bharat-Args Research Centre (BARC) General Chronicle Examination (GCE) 2020 for Electrical Engineers (EE) was a significant milestone for many candidates. This article provides a thorough analysis of the paper, highlighting the key areas covered and offering valuable insights for future aspirants.

Overview of the BARC EE 2020 Examination

The BARC EE 2020 paper was designed to challenge and evaluate the comprehensive knowledge of electrical engineering students. The paper comprised 15 major topics, which were distributed across several subjects.

R?thlocons and Stability Criteria

The first major section of the paper focused on R?tthlocons and Stability Criteria. This section is crucial for understanding the behavior of electrical systems and their stability. Key concepts included:

R?tthlocont stability criteria Nyqu?st plots Final and Initial Value Theorems Steady-state error Types and orders of systems

While some candidates found this section challenging, the problems were generally well-structured and clear.

Machines: Diverse Topics and Challenges

The second major section of the paper covered a range of topics related to machines. This part of the exam included:

DC motor and generator questions DC torque and EMF Speed vs. Load characteristics of series DC motor performance on AC supply Synchronous motor and induction motor Mechanically coupled transformers Efficiency regulations Rotor input of induction machine

This section was regarded as "good" for many candidates, with a significant number of questions that tested both theoretical knowledge and practical application.

Powersystem: Theory-Heavy Questions

The powersystem section was marked as somewhat challenging, with more theoretical questions based on the protection and improvement of power factor. Key topics included:

Stability of synchronous machines Delta connection in synchronous machine circuits Theory of breakers Bundle conductor effects on characteristics and impedance

While this section required a strong theoretical foundation, it was relatively less practical in its approach compared to the previous sections.

Signals, Analog, and EMF: Minimal Coverage

The sections on Signals, Analog, and EMF were notably absent from the paper, with no questions posed in these areas. This suggests a focus on more core topics of electrical engineering.

Mathematics: Probability-Based Questions

A small section of the paper involved questions from Mathematics, with a particular emphasis on Probability.

One interesting observation is that some questions were directly borrowed or paraphrased from previous GATE papers, particularly questions on topics such as:

Voltage regulator using Zener diode

This highlights the importance of being familiar with previous year's papers, as they can serve as excellent resources for practice and understanding the patterns and types of questions that may appear.

Power Electronics: Predominantly Theory

The Power Electronics section of the paper was mostly theoretical, with topics including:

Properties and characteristics of diodes, carriers, and transistors (BJT, MOSFET, IGBT) DC converters theory

While theoretical, this section required a solid understanding of the fundamental principles and their applications.

Exam Strategy: Speed and Practice

To tackle the BARC EE 2020 paper effectively, aspirants should focus on two key aspects:

Speed: As the paper involves a high number of questions, the ability to work quickly and accurately is crucial. Candidates should practice solving problems at a faster pace to ensure they can cover the entire paper within the given time limit. Practice: Regularly practicing past papers and reviewing concepts can help in building speed and confidence. It's important to not try to learn everything in the last minute but to focus on executing the questions efficiently.

Additionally, aspirants should prioritize areas of the paper based on their strengths and weaknesses, ensuring they allocate more time to challenging topics while maintaining a balanced approach.

Conclusion

The BARC EE 2020 paper was moderately challenging, with a mixture of theoretical and practical questions. By understanding the key topics and focusing on efficient study techniques, candidates can better prepare for future exams.
