# Study material for SSE/JE examination by RRB on Electrical Engineering Part I

#### DC Network Theorems

A network always is required to calculate the electrical parameters in a circuit consisting of voltage and current source, resistance connected in different combination, etc. In order to simply and systematise methods for solving these circuits, different theorems has been developed and one should be aware of it. These are

Kirchhoff’s law: There are two laws namely Current Law and Voltage Law. Current law states that the algebraic sum of the current meeting at a point is zero and voltage law states that the algebraic sum voltage source and drop in a closed circuit is always zero. Algebraic sum means direction is taken into consideration.

Thevenin Theorem: It provides a mathematical technique for replacing a given network into a single voltage source and series resistance as seen through the two output terminals.

Norton Theorem: On similar lines to Thevenin Theorem, Norton theorem converts the network by a current source and parallel resistance.

Delta/star Transformation: In many networks, by converting star into delta or vice-versa, the solution of the circuit becomes simpler.

Thanks a lot for this. Waiting eagerly for Mechanical and Civil too..

Thank you Sir.

Awaiting mech and civil….

Abhishek, I am a free lancer and feel happy in helping others with what little I know or I can do. all this material is not available readily with me. I am preparing, understanding and con-sizing to benefit you all. So first I have to complete electrical engineering which will take another week and than I proceed on other content. Please don’t depend on me alone for the content on other subject. I am not very sure if I will complete. However, I will be posting mock drill questions for you all shortly.

Thanks a lot for your help sir.

thank u so much sir…from the starting i dont know where to start..but when i came to this site..i am getting ideas of where to start..thank u!!!

Thanks vino for the complement. I will request if you to share with your friends as well so that they are benefited. I am writing and posting study material and multiple choice questions to benefit candidates. Keep in touch with the website for new posts.

Mahesh sir, your effort is very appreciable…i know sir its very difficult for you to focus on other mainstream as well…but sir plzz can we have any sort of guidelines regarding SSE rrb civil..any course material?? becuse syllabus is too wide in civil engineeing..

if u could help sir..mail me at [email protected]

very eager to hear from u…thank you

THANK U SO MUCH FOR PROVIDING THESE MATERIAL IT IS REALLY USE FUL PLEASE PROVIDE MOCK TEST FOR MECHANICAL ENGINEERING ACTUALLY I DONT KNOW THE PATTERN OF QUESTIONS RRB JE/SE IF U PROVIDE SOME PREVIOUS PAPERS I CAN PREPARE SOME NOTES AND SHRE WITH U BECAUSE AM PREPARING FOR MECHANICAL ENGINEERING COMPETITIVE EXAMS [email protected]

Previous year papers mock drill is available on this website. You may visit https://www.railelectrica.com/practice-test-papers-sseje/previous-year-question-paper-of-sseje-conducted-by-rrb-for-on-line-self-examination/. There are three sets each for SSE and JE called red, yellow and green. Search and attempt the question papers and you will have a fair idea of the pattern of examination.

everyone is posting for all other branches except civil engineering…can anyone help regarding course material for civil engineering..plzz mail me at [email protected]

I am an electrical engineer by profession and therefore posted the content of study material sufficient for objective type questions. I hope you know that you have to study electrical as well for civil engineering job exam as well.

Hell sir,

I just know about you, that u help everyone for his carrier..

So I need your help.

(my education qualifications is- 10th passed under WBBSE, after that I am going to complete my diploma course in electrical engg in 2016,)

I decide to sit in upcoming RRB’s ALP and JE exam..

Will you please help me to complete the large GK syllabus, because I don’t know from where or which topic of gk comes in rrb exam, or is their any book for rrb’s gk preparation which is recently popular in market? This ‘gk’ is my problem to crack the exam.

I am so asking because I forget every thing after learning, I like to read by understanding..

I want make my carrier in Indian railway, pls help me..

It is good that you have decided to prepare on the subject now itself. At this stage, just do following things: 1. Read newspaper daily and makes notes of interested developments. There are many website making questions on the current affairs. Generally current affairs is given importance in any examination. 2. Read your class 8th maths and 9th-10th science books for fundamentals. Develop skills in multiplication tables. Prepare technical notes of your diploma classes which can fit in for multiple choice questions. I will be posting multiple choice questions mock drill tests for people like you to test in between your preparedness.

Thank you sir,

Thanks for advise…but according to new syllabus of RRB JE, not only from electrical trade but all trade’s question will be set in the technical part of question. Then my questions is that, how I prepare the other trades question?

I mean the question will be set from Either all the 3 year’s syllabus of other trades Or only few important subjects of other trades.. Please help me sir.. I have no idea in it..

If you have any recent RRB JE question paper then please attached it on your website..

The syllabus for JE and SSE as well as Assistant Loco Pilot is same irrespective of the branch he has done his ITI, diploma or Degree. The questions are generally such which one has studied of all the branches. For example while doing BE every one studies some part of the engineering of other branches also. I will be posting the question bank of RRB JE after some time.

Mr.Mahesh Kumar jain could you please tell me which publication or author book is best for preparing RRB sse & je examination for technical & non-technical.

I don’t think any one book can be useful. I suggest you go through the Class IX and X books for JE Science, and Class XI and XII science books for SSE. Read and familiarize with the concept given Class VI and VIII arithmetic. For Technical part, go through your notes prepared during I and II year of study. For other subjects, many books are available. This should be more than sufficient.

hi sir, i would like to know the cutoff marks based on last year notification for SCR SSE & JE.

And also the inhand salary of them.

I don’t have the cut off of SCR with me. But in any case, you should work of minimum 70% to ensure your making a place in the panel.

Sir what was the cut off marks for SSE under general category in 2014 for RRB Secunderabad.

How does it matter Syed? Will it help you in your preparation? Unless you plan for 70%, chances are bleak.

sir plz can I have last 5 year question paper on following

The examination is not held every year. The question paper is not given to candidate after the examination. During the 2014 examination, the RRB has uploaded the paper on their website. The same are available on this website.

hello sir .. i m a b.e electrical passout. wantd help in tech sction of competative exams. pls help sir. or tell me if there is any you tube channel to help me.
