plz send me previous papers with answers
this site is very good for all
a speed can be measure with ___________
send privious papers……………….
plzz send mee last year question paper thanking uuu
please send previous transco papers
frds plz send me ap transco/apgenco xam papers as well as impotent materials….
iam prepareing 4 ae n sub engg plz……………. help me mail me on ethendra.eee@gmail.com
pls send me the previous questions and answers in APGENCO exam
shakunthala posted this q…that
Whatt-hour is a itegrated or obsolute
ans} watt-hour meter is also called as energy meter … it can read the energe and also record it for feture use …because of this reasion it can be called as itegrated meter . e.g our house service meter .as for as i know i posted this ans ..if it is wrong then mail me to ganesh.gomavarapu@gmail.com
Control of the water in Hydel power plants by—Penstock/Bypass/Wicket
ans}wicket
results r out check u r result at this website apgenco.cgg.gov.in
i got selected
when results coming
when will be the results?
Genco SubEngineers written test results will be in the 1st week of April
1. Flame scanners are used for
A. flame fire
B. RH
C. SH
D. Non
RH,SH mean ? plz send comment
2. Healthy flame in which color
A. gold orange
B. blue
C. white
D. Red
comment
Gold orange color mainly in corbon material i think its wrong
Blue color mainly Gas, electric stove in heating element using tungsten that’s why glow in Gold orange color, mainly its Blue. Ex:- Electrons passing in two electrodes in B/w Persian blue color
3. The dangerous thing in steam boiler is
A. Less water level
B. Leakage in super heater
C. Economiser
D. Airperheater
comment ?
……..
