BHEL(ET) PREVIOUS EXAM PAPER for Electrical

Monday, 1 August, 2011
Published by Roma Rahul Gupta for Chhattisgarh Online


BHEL(ET) PREVIOUS EXAM PAPER for Electrical check here:
This previous paper is totally based on candiadate's experience.
BHEL(ET) PREVIOUS EXAM PAPER for Electrical
The entire test paper consisted of 240 questions with 5 options for each question and -1/5 marks for wrong answer with 1 mark for right answer.
The paper consisted of primarily four sections

1) Technical Engg (60 Questions)
2) Basic Engg (60 Questions)
3) Verbal Ability (60 Questions)
4) Quantatitive (60 Questions)

I think to crack this test you have to take the following steps:
The Aptitude portion (English, General math & Reasoning; 120 questions) 


The Technical portion (Electrical (approx 80) & General Engg (approx 40); 120 questions)
Electrical Engg paper has around
1) 15 Questions from Electrical Machines out of this 10 numericals.
2) 8 Numericals from Control System
3) 4 Numericals from Instrumentation
4) 15 Questions from Electrical Power out of this 8 numericals
5) 8 Questions from Circuit and field theory
6) 10 Questions from Electronics (Power & Digital)


General Engg paper has around
1) 35 Questions from mechanical engg
2) 15 Questions from Physics
3) 10 Questions from other general engg
Non Technical paper is very easy.
To solve this paper, speed contains an important factor. We have only 35 seconds to solve a question.
So be fast and All the Best 


For Technical Portion


Completely solve all the chapters of ANY ONE OBJECTIVE Electrical Engineering GUIDE


·  J B GUPTA


·  GALGOTIA PUBLICATION- OBJECTIVE Electrical Engg.





1)      Solve all the objective questions  which are at the back of these books





·         P S BIMBHRA-ELECTRICAL MACHINERY


·         P S BIMBHRA-POWER ELECTRONICS


·         B L THERJA


·         C L WADHWA-POWER SYSTEMS





Go through the previous 10 year GATE questions which are conceptual in nature. You need not practice lengthy and calculative type questions because you can’t solve them in this test as the time is quite meager. Better leave such questions and move forward.


For General Engg: Basic Physics & Mechanical Engg.


For Non Technical Portion


Golden Rule: Attempt Non Tech portion first.


Questions would be on basic maths and reasoning. Try to attempt as many here.


There are only three ways to bring proficiency in non technical area.


·       Practice


·       Practice


·      Practice


 Books recommended are:-


1. M Tyra


2. Made Easy: Aptitude and Reasoning Book


3. Baron’s GRE (Comparison type i.e inferential questions) 20 questions will be from this book.


For Reasoning you may refer any book like Banking recruitment Guide,


MAT Guide etc.





For English: Be thorough with basic grammar and have good reading skills.


Important Points to Note


* Handle Aptitude first (it helps).


* Avoid (seemingly)difficult or long questions in technical part. There are lot easier questions dispersed all throughout (more towards the end). Try them, each will fetch you equal marks. Ultimately, its the total count that matters and not the type of question you got correct.
