For CSE and IIT aspirants

Electrical Engg Strategy

In Uncategorized on August 7, 2010 at 5:39 pm

Paper – I

  1. Circuit Theory: In this topic one should be fast in solving problems. Best way to gain speed is to practice regularly from IES papers of both electrical and electronics. Do questions from single IES paper (there are 3-6 questions every year) within time limit.
  2. Signals and systems: Here also speed is important. It is better to make a formula sheet and revise it regularly. For DFT/FFT, refer to Oppenheim’s book on DSP.
  3. E.M. Theory: Read chapter 6(till 6.29), 7 and 8 from K.D. Prasad. For Smith chart and impedance matching refer Jordan & Balmain. Make the list of formulas and practice all the derivations.
  4. Analog Electronics: Diode, Transistors and Amplifiers can be done from any book. Topics that are to be covered from JB Gupta are: Oscillators, Op Amp, Wave shaping circuits, Multivibrators, Waveform Generators and Power supplies.
  5. Digital Electronics: Mano is sufficient for the part of syllabus which it covers. For topic left like Timer (look at chapter on 555 IC Timer), Comparator, S&H circuit refer to JB Gupta.
  6. Energy Conversion: Try to cover everything given in the syllabus from Ashfaq Hussain and make good command over all the numerical given in the book. It covers topic from IES point of view. Do all the questions asked in the IES exams thoroughly.
  7. Power Electronics and Electric Drives: Topics to be covered are Chapter 2(characteristics of diode, BJT, MOSFET, IGBT), chapter 4-Thyrister(complete), chapter 5 – Thyrister commutation techniques (complete), chapter 6 –Phase controlled rectifiers(Leave dual converters), chapter 7- Choppers(Leave Thyrister Chopper circuits and multiphase choppers) , chapter 8 –Inverters(Leave force-commutated thyrister inverters, current source and series inverters) and chapter 12-electric drives(complete). Cover all the derivations (like deriving expressions for particular type of rectifier or inverter) as well as working of circuits.
  8. Analog Communication: Cover chapter 4(AM) and Chapter 5(on FM and PM) from BP Lathi. Random process(chapter 1) can be covered from Haykin. And Noise(chapter 4) can be covered from Singh and Sapre. Also cover AM AND FM practical modulation and demodulation circuits from Singh and Sapre.

Paper II

  1. Control Systems: Nagrath and Gopal is sufficient for all the topics. Practice from previous year IES and CSE papers.
  2. Microprocessors and Microcomputers: Cover chapters 1 to7 and 9, and parts of chapter 8 and 10(from which questions has been asked in IES exams), In peripherals cover 12, 14, 15, 16 (Focus more on whatever has been asked in IES papers).
  3. Measurement and Instrumentation: Cover all the instruments given in the syllabus thoroughly from the Sawhney. Here also guide will be IES questions.
  4. Power Systems: I did this topic from Nagrath and Kothari as I already had covered the book in graduation. Practice solved examples of both Wadhwa and this book.
  5. Power System Protection: Chapters of Protective relays and circuit breakers (from Wadhwa) cover large part of the syllabus in much better way. For microprocessor based relays refer to TMH book.
  6. Digital Communication: For PCM, DPCM, DM refer to chapter 6 of Lathi. ASK, PSK and FSK are covered much better in Haykin. Information theory and codes can be covered from either of them. Chapter 1 and 2 of Forouzan are to be covered for data networks and 7 layered architecture.
  1. Thank you so much….

  2. Hi Prakash,
    thanks for the detail strategy. . I will be so kind of you to upload few of your sample answers. Also, Please tell the exact title of following books:

    1. Simon Haykin
    Is it Communication system OR
    An Introduction To Analog And Digital Communications.

    2. K.D Prasad
    Is it ‘antenna and wave propagation’ ?

    Which all chapters are to be done from Nagrath & Gopal for control system ?

    Lastly, The chapters to be done from oppenheim book. . both for SS & DFT/FFT.

    Thnx. .

    • @mayuresh: it is communication systems of haykin. its not antenna book of kd prasad(i am not sure of exact title though). cover the chapters which contains syllabus for both control and signals.

  3. hi…
    what is the book that has to be referred for power electronic and electric drives… you have mentioned the chapters to be learnt.. Could you please specify the author of the book ..

    thanks in advance

  4. @ krishna

    The author of book is P.S Bhimbra and the title is Power Electronics.

    Kindly go thru the books list post. .

  5. Dear Prakash,

    First of all, Thanks a million for the strategy!
    I have a question though, How did you verify your solutions while practicing IES/CSE papers ?

    Please upload sample solutions of Electrical paper as well, like mathematics, indeed it is time consuming, but will certainly help large audience here.

    Thanks a lot..

    • @raju: i did not verify. you need to be sure of yourself. yes i will upload sample solutions of ee too.

  6. Hi Prakash,
    Thanks a tonne for this detailed strategy.
    I have brilliant tutorials IES study material, should I cover the material side by side or after completing the whole course as per strategy suggested by you?
    Thanks!

    • @aditya: if you cover these books thoroughly you will not require any material.

  7. Thank you so much for the strategy!
    Just one question: Should we practise the IES and IAS exam questions when we are covering the syllabus the first time or should we practise only books questions now and go for speed increase and exam questions practice during the second round?

    • @utsav: i forgot to mention this important point. you need to practice them at both the stages. for 2nd round you can practice 4-5(preferably cse papers) full length papers

  8. hello sir…majority of the student being from electronics background are findin a bit tough to get to know electrical sub..it would be gr8 if incase u can mention the exact chapters to be covered ( as u did for power electronics )
    for ENERGY CONVERSION,POWER SYSTEM ANALYSIS & POWER PROTECTION AND ANALYSIS
    Thanks!!!

  9. Hi Prakash,
    Thanks for your response. Just one more quick question, in power systems you are suggesting Nagrath&kothari, are you referring to modern power system analysis by nagrath&kothari or some other book ?

  10. hi prakash ji,
    thank you very much for the detailed strategy.

    one thing i observe is IES questions are shorter in length than those of CSE for similar marks. and quantum of theory questions is also less in IES. it means we need to solve IES papers in lesser time. isn’t it?

    • @babu: yes you are absolutely correct. you need to solve ies questions in much lesser time(2/3 of cse paper)

  11. Hi prakash
    How much would be the scaling for engg subjects like electrical engg.

  12. Hi Prakash,
    Thanks for the strategy..
    till which month we shd be finishing the electrical suject for 2011?
    And Is there any test series for electrical subject?

    • @pritam: it is upto you to decide on timeline. ideally you should complete it before prelims. i dont know about any test series for electrical.

  13. One more question Sir…
    Were all the questions tht came in mains was from solved examples of above mentioned buks?

  14. Also sir, for digital electronics..two buks are there of moris mano…one is of pearson publication and other prentice hall of india publication…which one shd we go for?
    thank u and sorry for so much questions…

  15. i am in 7th sem btech.
    how to manage time between college(8am to 5pm) and studyn for ias.considering the fact that engg subjects too are very difficult.so please guide me how to manage the time.
    and where shal i take coaching from

    • @surbhi: i did not go through similar situation as i started preparation after graduation. try to manage on holidays. you can take coaching from delhi.

  16. Have you practiced IES question papers, both objective and subjective papers or just subjective papers? Till how many previous years question papers did you practice?

  17. Sir can u please tell from where u got the list of books when u started preparing for this exam. Actually i am finding difficulty in selecting books for mechanical engineering.

    • @avinash: i got the booklist after consulting various sources. infact jawahar book depot can also suggest which book is popular.

  18. Hi Prakash,
    Happy Independence Day

    Could you please help me in Q. 3a) part -ii of Electrical Paper-I 2009?
    This Q. is regarding the given V-I characteristics & we have to implement it using ideal diode circuits.

    Thanks

    • @sunpreet: sorry, i did not attempt this question, neither was i able to do it correctly after the exam.

  19. Hi Prakash,
    Can u pls mention the name of the book and publication for J B Gupta..
    Thank you…

  20. Thanks Mr Rajpurohit for your kind guidance.Hope it will wipe away all doubts.I would be following it sacrosanctly and if any problem arises,I would like to seek your kind help.Please assist me in that time too.

  21. One more question-which book to be followed for analog and digital electronics by j b gupta?what is the title of the book by singh and sapre?

  22. Communication Systems(Analog & Digital) – Singh & Sapre (TMH)
    Electronic Devices and Circuits – J.B. Gupta (S. Kataria & Sons)

  23. hello sir, plz provide Strategy for mathematics also, and also plz tell me how are u manage ur time for study math,electrical and GS.(as u spend 1st few months on math and electrical then work on GS or u take all three together??)

    Thank U

  24. Hello sir,
    please can you let us know the individual chapters to be studied from electrical subjects for ENERGY CONVERSION,POWER SYSTEM ANALYSIS & POWER PROTECTION AND ANALYSIS from the books mentioned by you…
    thanks a lot!

  25. Dear all with Electrical engg. optional,

    I cleared prelims (net Pre score – 65 in electrical and 50 in GS = 212.5 marks category OBC)
    I have been writing this exam for the last two years.
    This is my 3rd attempt with Electrical.
    The main problem I faced in my earlier attempts is the very few no. of people attempting with Electrical Engg. It makes difficult to check the answers and also finding the worked examples from which book the questions have been asked after mains. As usual, We may be thinking that our answers are right and finally landing up in scores around 250 or less.
    Cross checking of answers and discussion of questions will be helpful in assessing scores pragmatically and also for improving our performance in next attempts.
    So far, there is no active forum of serious aspirants with electrical optional.
    First time I’m finding many aspirants with electrical optional in this blog.
    Prakash sir may become busy after starting of foundation course. My appeal to u all is that we can use this blog as a way of communication in our preparation (With permission of Prakash sir). Plz let the blog active and rocking..

    All the best..

    Babu

  26. Hi Babu…

    We can start a community in orkut for tht…
    Wht was ur previous two year scores in mains for electrical option?
    And wht went wrong in those two attempts..|It wd be great help if u can share ur experience..thank u..bye

    • hi Pritam Maske,
      thanx for ur response.
      no doubt, We can start a community.. i’ve even searched for such community in orkut. one is already there but dead. no inputs or sharings etc. therefore i thought of using this blog for interaction.
      last time i got 226 (107+119) out of around 450 marks i’ve attempted correctly. culprit is selective preparation.
      i’ve left communication, signals& systems totally and partly EMF.
      that priced heavily for me.
      u can reach me at: babuarts@rediffmail.com

    • Dear all,
      “Electrical 4 UPSC” orkut community is created for the use of all serious aspirants. interested may please join:

      wishing you All the very best,
      regards
      Babu

  27. hello sir, just reiterating the above req once again.. please can you let us know the chapters wise break up for the electrical subjects as u have done with Power Electronics
    ENERGY CONVERSION,POWER SYSTEM ANALYSIS & POWER PROTECTION AND ANALYSIS…

    @pritam,babu
    Nice suggestions… we need to keep this blog ( future community ) so that serious canditates may have a smooth transition with their doubts..

    Thanks again for Prakash sir, for having our ques ans and in the melee filling us with Hope…

  28. Hi Sir

    how many hours did u study and for hw many days to get 2nd rank in ur 2nd attempt…do u think that studying for 10 hours a day from now on till mains of next year with maths and physics as optionals will be sufficient to clear this exam(CSE-2011) with a top rank of under 3..?? please tell me..i will be very obliged to you

    • @alok: for 1st attempt i put 10 months and in 2nd i put 5 months. how could i tell time required for any other person?

  29. Thanks Prakash for the wonderful blog! I was wondering if it would be possible for you to share a sample answering attempt like you did with Mathematics.
    All the best!

  30. Thank you sir…. !! can u also tell how to keep focus on the studies through out the period.. i mean like shud we study fr continuos long hours at a stretch or wil it be beneficial to study in parts.. hw many avg hours per day did u devote to study..and what was ur daily skedule could u elaborate ..i will try to follow it wid discipline.. please reply

    • @alok: see all the successful candidates have different schedules and no particular schedule fits for all. it is better to make individual schedule depending on your preparation level, optionals.

  31. dear praksh,
    can you please for how many marks you attempted correctly in elctrical engg.

  32. @sri ram
    he has given every detail about his 1st and 2nd attempt,atleast take the pain to go through the whole blog,and then ask questions…..

  33. Sir as u have advised to drop chapters topicwise,i would like to know whether we should do it confidently as the xams are drawing near.plz reply.

    • sir could you enumerate the strategy for ies exam, coverage required, and the score needed to get a rank in top 5. also what are the job prospects in engineering services

    • @joyanto: i am sorry, i could not get your question

  34. Sorry.i wanted to know whether we should leave the chapters/topics in respective topics as u mentioed in the strategy e.g.waveguides in emd

  35. Hi Prakash,
    congratulations!! Ive been following ur blog since ur success..its of gr8 help! few quick ques…
    1.where can i find genuine syllabus..upsc portal show entire elecronics(microwave,radar, IC fab..n much) too as part of syllabus..ques based on scada,rtu,engg materials??2004 paper was based on that syllabus..even in control system, tuning of discrete PID controllers was asked)
    2.should i stick to the syllabus..(for ex. should i study about various powerplants in ps?)
    3. kindly suggest me links to get previous upsc electrical papers as i could find only few!
    in desperate need of ur suggestion..tnx a lot in advance!

  36. All aspirants are grateful to prakash sir for sharing his strategy…

    thank you sir

  37. Sir, iam a beginner.i’l give my exam in 2012.suggest me some books to get good basics before starting electromagnetic field theory.
    Also suggest me a better approach for EE optional considering the time in hand.

    thank u

    • @phani: i have given the book in booklist and this strategy is common for all irrespective of time in hand.

  38. sir,though u have got good marks in 2008 attempt, why were u not selected for ias?? i.e.(390 in maths, 140+134 in g.s, 105 in essay)

  39. sir, is it enough, if one gets around 340 in elec. and a compromising score in other subjects to get into ias??

  40. Hi Prakash Sir!

    I am in 4th yr. right now and I want to prepare for IAS while doing MTech from IIT Delhi. Is it possible to do both side by side?

  41. Can anyone please tell me the name and publication of the book by kd prasad ????

  42. SIR..U MENTIONED CHAKRABORTY FOR CIRCUIT THEORY..DO WE NEED TO COVER ENTIRE BOOK?? MOST OF THE THINGS ARE NOT THERE IN SYLLABUS

  43. sir i m ece background student and sir i want to opt electrical engineeering as main subjct for cse 2014 mains….can u tell me after the changed pattern of cse, is it correct option for me(as i m an ece background student), and can i leave core electrical engineering subjct such as power system and electrical machines etc which are not in electronics during my preparations,,as i see in previous year papers all questions are not compulsary….please guide me regarding this

  44. Sir,
    I’m about to pursue btech in electrical engg and will opt the same and pub. admin. as optional subjects in the upsc exam.
    Is it possible to crack the exam by studying frm a non iit/nit college, considering the quality of lectures, libraries and other resources in these colleges.
    Can u please suggest me some steps which would make my preparation less arduous?

  45. sir i am seleected in IES 2007 with 21 rank . now new format of syllabus has come , so will it be advisable to go with electrical as optional ….and how difficult it would be to prepare gs with electrical in this changed situation,,,, pls reply sir

  46. This website certainly has all the information I wanted about this subject and didn’t know who to ask.

  47. Hello Sir,
    I am UPSC aspirant and wish to take electrical engg as my optional for 2013 mains. I have not started preparing yet. I have been consistently advised not to take this optional as very few have scored well in this subject.Is it possible to cover the syllabus in 1 and half months, and can you suggest any material for model answers?

  48. hi,prakash,,,,many many congratulations for ur achievements,,,..if there would have been two optionals then i would also have taken mathematics and electrical….but i want to ask u in ias….which of these two is more scoring…..does both have same scaling in marks…….
