Добавлен 19 июн 2013
The primary objective of this channel is to assist the students of electrical engineering for self learning. Students can use these videos for preparing and revising the subject matter at home.
Every possible care has been taken to eliminate the errors. Still, the possibility of some errors left cannot be denied. Any information regarding errors along with useful suggestions will be gratefully accepted.
I hope these videos will satisfy the needs of Electrical Engineering students and will help to improve the overall teaching and learning process.

Easy Explanation. Thank you sir ❤❤
Excellent work, do you have a video or reference on a scenario where the voltage ratios are different and impedance is different and kva is different. I am interested in the math behind calculating the circulating current values. Thanks for all your hard work!
Best explanation I have ever seen, and I’ve studied a lot, thank you very much!
Please make video on synchronous machines
How does the Ia/4 apply to armature resistance? Would this be the same as a parallel resistor network? Thanks
❤
So lengthy lecture 😢
Lectures on machines 2 needed
🤌🤌🤌🤌
Sir why is input power not V1I1? Why are we taking the cos component?
Can't express in words how much good your explanation. Live long.
we need more videos please
Thank you from South Africa
Thank you Sir! From Philippines.
Nice 👍
28:55
Please upload more videos on alternators and ac machines.
please make a video on semiconductors
please make a video on induction motor
Thank you providing this knowledge for free.
❤❤
Done 🎉
Nice job professor. A nice review for me. Thank you for your help.
tq
Great explanation sir thank you so much
Great teacher 😁
Thank you so much
you are so good at example things clear
Excellent video
Hello sir, is the power factor always 0.8? if not, how do we determine it when not provided in the example?
if not given enough information you can assume unity pf
Very informative lecture sir ❤
Sir, pls upload synchronous machines
You are brilliant sir ,,need more maths on this topic ..plz sir😔
Good explanation ❤
Sir upload more videos about other electrical subjects
❤❤❤
osm 👌 explained
Nothing understandable
Do you have electrical master degree course on line?
excellent
Sir I have 45 kw , 4 poles ,54 slots, 54 coils 162 segment double layer winding DC Motor. How to divide pole pitch or Overage pitch , Back pitch and front pitch, please tell me sir.
excelleentt thank you so much!!!
thank you so much! you've helped people across the world, even Egyptian students are watching your tutorials
Sir please upload the three phase induction motor and single phase induction motor.
your presentation is outstanding sir .its very helpful for us....
Thank u very much sir
How Sa will be leading p.f.
in the second question first equation isn't it 0.9Wi + 0.9Wc = 0.1
とても良い動画です。
Is it not the percentage of full load voltage?? According to BL Thereja bok, it is pecentage of full load voltage..
thanks
