#### CIVIL GATE Practice Questions With Solutions Volume-1

Solutions of all previous GATE Questions are already available. Every year about 20% of questions will have repetitive nature. However, rest of the questions are from untapped areas (never asked areas) and few from Previous Engineering Services & Civil Services Questions. Keeping this in view, possible questions are prepared in various subjects (chapter wise) along with their hints/solutions. The student is advised to practice the questions systematically so that their chances of getting high score in GATE Exam will increase.

The student is advised to solve the problems without referring to the solutions. The student has to analyze the given question carefully, identify the concept on which the question is framed, recall the relevant equations, and out the desired answer, verify the answer with the Final key such as (a), (b), (c), (d), then go through the hints to clarify his answer. This will help to face numerical answer questions better. The student is advised to have a standard text book ready for reference to strengthen the related concepts, if necessary. The student is advised not to write the solution steps in the space around the question. By doing so, he loses an opportunity of effective revision.

As observed in the GATE Exam, number of sets may be possible, being online exams. Hence, don’t skip any subject. All are equally important.

It is believed that this book is a Valuable aid to the students appearing for competitive exams like IES, JTO, DRDO, ISRO and Other PSU’s. This book can also be used by fresh Teachers in Engineering in improving their Concepts.

#### ESE – 2019 Prelims Electrical Engineering Objective Volume 1

The Stage-I (Prelims) of ESE – 2018 consists of two objective papers. Paper-I is of General Studies & Engineering Aptitude. Paper-II is of Electrical Engineering of 300 Marks and 3 hours duration. In stage-II (Mains), the technical syllabus is divided into two papers. The subjects included in this volume are:

- Engineering Mathematics 2. Electrical Materials
- Electric Circuits & Fields 4. Electrical & Electronic Measurements
- Computer Fundamentals 6. Basic Electronics Engineering

Keeping in view of the above topics, the present Volume-I for prelims of new pattern is redesigned using the previous questions from 1992 onwards.

The style, quality and content of the Solutions for previous ESE Questions of Electrical Engineering, will encourage the reader, especially the student whether above average, average or below average to learn the concept and answer the question in the subject without any tension. However it is the reader who should confirm this and any comments and suggestions would be pleasantly received by the Academy.

It is observed that majority of ESE objective Questions are being asked as it is in many PSUs, state service commission, state electricity boards and even in GATE exam. Hence we strongly recommend all students who are competing for various competitive exams to use this book according to the syllabus of the exam concerned. This book can also be used by fresh Teachers in engineering colleges to improve their Concepts.

We proudly say that questions and solutions right from 1992 onwards are given in this book. The questions which appeared early 90’s are most conceptual oriented and these are being repeated in the recent exams in a different way. Hence we advise the students to practice these questions compulsorily. The student is also advised to analyze why only a particular option is correct and why not others. Evaluate yourself, in which case, these other options are correct. With this approach you yourself can develop four questions out of one question.

The student is advised to solve the problems without referring to the solutions. The student has to analyze the given question carefully, identify the concept on which the question is framed, recall the relevant equations, and out the desired answer, verify the answer with the anal key such as (a), (b), (c), (d), then go through the hints to clarify his answer. The student is advised to have a standard text book ready for reference to strengthen the related concepts, if necessary. The student is advised not to write the solution steps in the space around the question. By doing so, he loses an opportunity of effective revision.

#### ESE / GATE / PSUs Numerical Ability, Theory & self practice questions

The study material for Numerical Ability is thoroughly revised this year to meet the requirements of all categories of students. It consists of

(i) Brief synopsis covering the entire syllabus

(ii) Worked out examples, concept wise

(iii) Practice questions

The students are advised to go through the theory duly understanding the worked out examples to the extent possible and practice the questions, By doing so, the students will get familiarized with some of the concepts and can really enjoy the lecture in the class. Also, the students can interact with the faculty in a better way.

Thanks to all professors who extended their services in the preparation of this booklet.

It is believed that this volume is also a valuable aid to the students appearing for competitive exams like ESE, ISRO, State and Central Commissions and other PSUs.

#### ESE 2019 Prelims Basics of Materials Science & Engineering
