very helpful in key for genco
copy all the quations and key
ans for 90 is golden orange
i need apgenco subengineer exam question paper 2011
some ans in this key wrong so dont belive this type of key's
pls tel me the result date of sub enginer 2011
very helpful for electrical students
thanks to providing key
pls tel me the result date of sub enginer 2011
yes some of the answers are wrong...i think 10questions...some of them are 6question answer surgetank and 16th one answer is transformer and 22nd answer is motor and 82 answer is ms-excel.........this are memory based questions and answers so be carefull
pls tell above comment answers are correct are not...when will be results
for 6 question the answer is penstock not surge tank bcoz surge tank is used only for avoiding water hammering effect in penstocks. the conduit is nothing but a pipe r tunnel so the answer is 100% penstock .
for 16 question the LAs can be placed at busbars and transformer.
for 82 question u will not get any option in MS excel like to create a table u can create just borders for the cells.
thanks for u comments and give the comments if u people have any doubts.
the results may be declared in this week but not sure.
hai frnds. sub engineer exam put just for formality. . all those jobs were already buied with 7lacks some people... so dnt hope for jobs in apgenco..... work hard for other exams......
who said dear...nothing like that 2008 lo i got subengineer job ala emi ledhu andharu cheptaru but thats not true...so frds hope for the best
even for apcdpcl the same talk came that they sold that post for 2 r 3 lakhs...but my frd got A.E post
hai... nenu kuda vinnanu.. jobs sold ani... results vaste telustundi frnds... results may b last of this month.... all d best guys......
pls give correct answers for these questions..
1.Flame scanners are used for..........
2.Healthy flame in which color........
3.The dangerous thing in steam boiler is.....
4.The service voltage in power house.....
5.In direct arc furnace -----------is more.....
6.The angle b/w rotating field flux and rotor...
7.LV relays are used for protectin.........
8.Gates near the turbine-----------
and what about 92 t0 100 questions?
All are memory based questions so 100 questions are impossible
results when?
s frnd apgenco team worst... jobs sold in karimnagarrrrrrrrr.....
who said sold ani....resluts inka raledhu ani aa?ala antunaru...results late gane vastayi inka 2 r 3 days lo vastayi chudandi
i am diploma in mech engg
i rememered questions i got =64 marks
diploma %=83.56
completed in 2008
can any tell me whether i will geta job or not plz post me
@prasad,
according to my knowledge the vacancies are less, so 64 marks are good but not a big score, the allotment of job depands on ur location means which district u belongs,if u got above 75 u may have the chance.k wait for the results all d best
when are the results?site chusi chusi bore kotesindi...in 2008 exam was on nov23rd and we got results on jan9th 2009...then y this year results are so late??????
hey apgenco stupids release d results..... 56days pass.. hw much time u need to correction and announcement...
contract labourers ki ravali ani they are fighting in apgenco so manaki ravu posts valaki velipotayi...so mana test reget chesaru they wont release our reults....juniour plant attendants exam cancel ayindi they wont kepp exam.....so all the best for other exams
results r out check u r result at this website apgenco.cgg.gov.in
i got selected
even i got selected electrical lo.....posts vunavi 190 but candidates 400+ how can it be possible
hey buddy those r selected candidates belongs to all branches 350 posts includng elec electrncs civil n mech
hey buddy i saw in electrical list they have given 450 candidates in that list...and again we have separate list for civil,mech.....and again in electrical branch they are going for 1:3 ratio
those we got high marks in 3 of them they are issuing orders
hey ya sorry i didnt seen it correctly whatevr u said is correct there were 470 members in electrcl even i belongs to electricl i got 68.7 i didnt hav exprnc n even i got 6 marks for 3rd column as i compltd my dip in 2007 do u hav any idea regarding how they select the candidates will they take top 198 candidts r will they take community wise top candidates if it happens mai tho gone baba coz there were only 4 posts in zone 4 for my category wat abt u buddy
i got 78 marks in wrtn test n my percntg was 82 percnt in dip shortlisted but iam not satsfd with genco adminstratn coz most of them didnt scrd much in wrtn test n didnt hav tht much prcntg in dip but they gain marks in terms of xprnc really its a damn **ckin process of selection
@vamsi,
the third 6 marks is for the completion of ur diploma, i.e, after diploma u ve completed 3 yrs for every year u ll get 2 marks, so u got 6 marks, the max marks are 10 only for that column.
@srinivas
i know that srinu but iam expresng abt the worst process of selection coz the persons who completed dip a long ago got an advntg over there the one who got good marks in wrtn n even in dip has not gettng enough chanc to plc there.do u know if he takes only wrtn tst marks like that in ae recrtmnt i will sure get a job coz there were only 8 members before me but due to this worst lengthy process i lost those 4 marks in tht 3rd column n 10 mks for exprnc due to which 63 membrs now ahead of me so iam in a dilemma whtr ill get ths post r nt n i dnt wnt to w8 stll 1 mre month as they had taken 2 mnths jst 4 postng wrtn reslts i knw they will take arnd 1 n hlf mnth
hey how did u know that 8members are there before you????
hey buddy i just saw each n everybody wrtn marks from tht shrtlstd pdf file n there were only 8 membrs
hey guys who belongs to bc-d category n from zone 4 post ur marks so that we can predict ourself the reulst startng frm my side
total 68.7
bc-d,zone 4,electrical
even other community students n frm other zones also post u r marks,zone,community n branch
sorry frnds its zone 5 not 4 iam frm warangal anybody frm sme place
Hey GATE score is necessary for APGENCO xam kyaaa....???
no need of GATE score in apgenco xam
when will be the notification of sub engineers?
when will be notification for subengineers
