NTPC Exam Placement Paper


Hi Friends,

I wrote the NTPC exam held on april 9th,2006(Electronics Stream)

I faced the problem of "knowing the syllabus and the pattern" of it before

the exam.I was not able to find the correct guidance in any of these grps.So

i thought I would share mine so that it would be useful for the future

aspirants of NTPC.


First 120 question on technical and 50 questions on general aptitude.

1/3 negative marks for all the questions.

2 hours exam.(No calculator allowed)

Question paper along with the key sheet should be handed over to the

invigilator after the end of exam.


About the Technical:

questions about diac,triac,buck effect etc.

Control systems,synchros,all basics and theoretical

computer NETWORKS:

(abt CSMA/CD,bridges,routers,Ieee standards like 802.3,etc.(abt ethernet))


(CMOS structure, functioning,)


(gates,negative logic,postive logic,nand,counters,etc.)

Sample question:write a particular number in BCD,or hex equivalent etc.)

cominational circuit design(no of gates required etc.)


led bias,tunnel diode bias,fet,bjt,feedback amplifier

properties,optoelectronic devices,class c amplifiers,multivibrators,band gaps

in Si,Ge.,intrinsic concentration etc.


abt ozone layer depletion (CFCs)

The total efficeincy of a thermal plant.


Amplitude modulation,FM Vs. AM.

Antennas :

Director,reflector in yagi uda,microwave frequency ranges,bands,

ground wave,sky wave,space wave propagation.In which media em waves travel


Microprocessor 8085,interrupt structure,architecture,memories,mapping

schemes,8255,interrupt controller(8259)(ICW1,OCW etc.)

hard disk,floppy disk access times

mangement science

abc analysis(inventory management)

signals systems:

fourier transfor,sinc functions,convolution

network theory:

resonant frequency formulae


a/d d/a converters,differentiators and integrators,instrumentation


digital communications:

fdm, tdm

I almost covered 95% of the topics.This is as far as I could remember.


About aptitude:



comprehension passages

aptitude problem solving skills(train probs,loss profit sums,ratios,etc.)

word analogies

fill in the sentences with the most suitable word type of questions.



Tips:Time management is very important. Since most of the technical questions

are theoretical,complete them quickly and do well in the aptitude section.

Individual cut off in each of the 2 sections is necessary.

i don't know the actual cut off though.

Any queries plz do ask me.
