DC Generator !! Important Mcq Questions !! JB GUPTA

This video provides all the important mcq question from jb gupta in detail ....

Question no 90, unfortunately you given wrong information. For finding of conductor we should be very careful. Since 1 turn has 32 coils so 6 turns have 32 × 6=192 coils. Now each coil has 2 conductors then 192 coils have 384 conductors . Now put in formula Z=384 so E= .06×8×250×384/60×2

sir u r helping those students specially who can't afford expensive coaching classes ... thank you and carry on....

[kanaksharma]

I love ur "hello everyone BTW GREAT LECTURES THANKS SO MUCH 😊👌👌👌👌👌

[subhash]

Thanks sir for such type of numerical based video in DC GENERATER.

[piyushkhetani]

Sir I'm very thankful to you for making such easy EE video for everyone. So thanks a lot. And yes in que 90 there is mistake

[kamranayubi]

For question no 93 I can explain in two ways one is theoretically and other is based on formula. If you are good in machine then you know big rating of machine like synchronous generator has more power than small rating of dc machine which has small size. So power is directly proportional to size. Now if machine are heavy it will run slow and if machine has less weight it will run fast. So size is directly proportional to power and inversely proportional to speed. If power will half and speed will half then ratio will be same.

sir, , we love your effort
please continue these

[Amar-hdig]

Sir..
AC & DC Network pr v concept aur sath me numerical batayiye...

[Chhotucomedyvlogs.]

Qn -90 me Conductor =coils*turns*2=32*6*2=384 Hoga
Tb aa Jayega 384 volt

[ompatel]

Thanks sir
JB gupta se generator ka pura video banaye plz..

[jyotirmoysahoo]

All videos are very nice
Please upload more mcq

[yogitech]

Sir ak basic electrical numerical questions ka BHI video bna dijiye ex. Type es type ke
Questions he - when the current in a coil is increased from 2A to 4A in 0.05 second, the emf induced in the coil is 8volt. The self inductance of the coil is..

[brijeshtiwari]

sir eddy current loss me frequency aur voltage ka kise effect padta h. plz sir is pr ek video bana do

[nitinlamba]

DC aur ac ke bare ma full jankari basic concept and numerical

[sachingupta]

Hi
I want to know
Eddy current loss depends on freq or not n next one what impact on hysteresis loss to change in freq

[sabiulislam]

Sir AE me iss type numerical a sakte hai mean itna bara keuki calculator use nahi kar sakte ? Plz reply

[JyotiKumari-gsoy]

Ap jo Z ka value nikale h wo no of turn h usme 2 se multiply kijiye

[NorthVSsouth-domj]

Bhai sahab jaldi jaldi video banayiye plz

[kamranayubi]

In question no 91 there is no clear information regarding lap or wave winding and also number of conductors are unknown so we can solve in different approach. E=B×V×l The value of B and l are given, only problem to find Velocity V use this formula V= π×D×N/60

[pratikgamit]

power system stability par bhi video banaye sir
