In fact that is the main reason why I am so late in writing a post on Electrical Engineering. I did not feel the need to provide any extra information other than what was mentioned on his blog.For the book list, please refer to: http://prakashrajpurohit.wordpress.com/2010/06/02/electrical‑engineeeringmains‑booklist/ (http://prakashrajpurohit.wordpress.com/2010/06/02/electrical‑engineeeringmains‑booklist/) The unit‑wise strategy can also be found at Prakash Sir’s blog (http://prakashrajpurohit.wordpress.com/2010/08/07/electrical‑engg‑strategy/ (http://prakashrajpurohit.wordpress.com/2010/08/07/electrical‑engg‑strategy/)). Below, I am reproducing his strategy along with some additions of my own. Paper – I 1. Circuit Theory: This topic requires continuous practice. One should solve as many numericals as you can from A. Chakrabarti. Even though I couldn’t do it due to paucity of time but solving IES papers may help. 2. Signals and systems: In this topic, one must remember the formulas by making a formula sheet. As Prakash Sir has mentioned, 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. Practice some numerical examples. Sometimes the book solves them in a long way, but you must do them in the shortest way possible. 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. You will have to practice numerical from IES papers since JB Gupta doesn’t have many numerical. Also, in this

Strategy For Electrical Engineering

In Uncategorized on June 21, 2012 at 23:30For Electrical Engineering, I personally feel that Prakash Rajpurohit Sir’s (AIR‑2 in CSE‑2009)blog has all the required information that one needs to know. In fact that is the main reasonwhy I am so late in writing a post on Electrical Engineering. I did not feel the need to provideany extra information other than what was mentioned on his blog.For the book list, please referto:

http://prakashrajpurohit.wordpress.com/2010/06/02/electrical‑engineeeringmains‑booklist/(http://prakashrajpurohit.wordpress.com/2010/06/02/electrical‑engineeeringmains‑booklist/)

The unit‑wise strategy can also be found at Prakash Sir’s blog(http://prakashrajpurohit.wordpress.com/2010/08/07/electrical‑engg‑strategy/(http://prakashrajpurohit.wordpress.com/2010/08/07/electrical‑engg‑strategy/)).

Below, I am reproducing his strategy along with some additions of my own.

Paper – I

1.  Circuit Theory: This topic requires continuous practice. One should solve as manynumericals as you can from A. Chakrabarti.  Even though I couldn’t do it due to paucity oftime but solving IES papers may help.

2.  Signals and systems: In this topic, one must remember the formulas by making a formulasheet. As Prakash Sir has mentioned, 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. Practice some numericalexamples. Sometimes the book solves them in a long way, but you must do them in theshortest way possible. 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. Topicsthat are to be covered from JB Gupta are: Oscillators, Op Amp, Wave shaping circuits,Multivibrators, Waveform Generators and Power supplies. You will have to practicenumerical from IES papers since JB Gupta doesn’t have many numerical. Also, in this

chapter practice derivations well and make sure you do not do mistakes in symbols.5.  Digital Electronics: I referred to R.P. Jain for this topic. It is a very good book that covers allthe concepts and also provides sufficient numerical practice. Please stick to the syllabuswhile reading this book.

6.  Energy Conversion: Try to cover everything given in the syllabus from Ashfaq Hussainand make good command over all the numerical given in the book. It covers topic from IESpoint 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 ofdiode, BJT, MOSFET, IGBT), chapter 4‑Thyrister(complete), chapter 5 – Thyristercommutation techniques (complete), chapter 6 –Phase controlled rectifiers(Leave dualconverters), chapter 7‑ Choppers(Leave Thyrister Chopper circuits and multiphasechoppers) , chapter 8 –Inverters(Leave force‑commutated thyrister inverters, current sourceand series inverters) and chapter 12‑electric drives(complete). Cover all the derivations (likederiving expressions for particular type of rectifier or inverter) as well as working ofcircuits. Note that this book can be difficult to read at first due to extensive coverage oftopics. But you must nevertheless go through it. At first, focus on the concepts. You mayleave the numericals at the back of the Chapters since there are sufficient solved examplesin the book. Do not just read the examples, solve them yourself.

8.  Analog Communication: Cover chapter 4(AM) and Chapter 5(on FM and PM) from BPLathi. Random process(chapter 1) can be covered from Haykin. And Noise(chapter 4) canbe covered from Singh and Sapre. Also cover AM AND FM practical modulation anddemodulation circuits from Singh and Sapre.

Paper II

1.  Control Systems: Nagrath and Gopal is sufficient for all the topics. Practice from previousyear IES and CSE papers. Please stick to the syllabus. There is no need to read the entirebook.

2.  Microprocessors and Microcomputers: Cover chapters 1 to7 and 9, and parts of chapter 8and 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 syllabusthoroughly from the Sawhney. Here also guide will be IES questions. In this book, you mayskip the numericals at the end of the Chapter if you have less time because it has sufficientsolved examples. Focus on derivations of different formulae. Also note the drawbacks ofeach measuring instrument. For oscilloscope, please do not forget to practice makingschematic diagrams.

4.  Power Systems: I did this topic from Ashfaq Hussain. It covers the entire syllabus. You mayhave to read a bit more on the last Chapter. Solve all examples and questions at the back ofthe Chapters. Do not forget to practice the flowcharts of optimization schemes for loaddistribution.

5.  Power System Protection: Chapters of Protective relays and circuit breakers (fromWadhwa) cover large part of the syllabus in much better way. For microprocessor basedrelays refer to TMH book. You may also refer to the TMH book for other parts of thesyllabus too in addition to Wadhwa. Do solve the questions at the end of the Chapters.

6.  Digital Communication: For PCM, DPCM, DM refer to chapter 6 of Lathi. ASK, PSK andFSK are covered much better in Haykin. Information theory and codes can be covered fromeither of them. Chapter 1 and 2 of Forouzan are to be covered for data networks and 7

layered architecture.

Basically in Electrical Engineering, practice numericals and revise your derivations well. Donot forget to memorize the advantages and disadvantages wherever relevant for answeringtheoretical questions. When you write answers always, mention which symbols stand for whatand express your answers in correct units.
