resistance of backward branch=r2/2-s (7.8/2-0.05)=4ohm
thanks me later😇😇😇😇😇
Thank u mam sir n to btaya hi nhi tha or mi formula search kr rha tha🤣
Thank you 🙏
Thanks
Thank you 😊
Thanks
Kindly Note:- Q.4 Answer is 4Ω i,e. effective rotor resistance in the backward branch of the equivalent circuit will be
R'b=R2/(2-s) ......... -> 7.8/2-0.05= 4Ω. Rest of the explanation is correct.
R'b=R2/2(2-s)..Answer is 2Ω
@@giridharkoncha6905 No.. what he said is correct
No rotor resistance in backward branch is r/2*(2-s)
In forward branch r/2s
sir I think Q.23 ka answer (A) hona chahiye...because no ralative speed means no induced emf in rotor hence no induced current so no flux generation so there will be no interaction of two fluxes so no torque generation in rotor.
Slip is 0 (ns-nr/ns) so no torque generation
Correct
Correct bro
U r absolutely right bro
Q4- resistance of backward branch= r/ 2-s.
r=7.8/2-.05= 4 ohms
Resistance of backward branch = r/2(2-s)
Answer 2 ohm
Wrong r2/2(2-s)
Sir , love from assam. I love your method . For me it's not only 50 questions its the most important questions of the whole topic and the main point one can easily attempt 70-80 questions from this 50 reference questions 🙏. You helped me a lot in our state power distribution companies exam . Thanks sir
Thank you so much for your kind response Jyotimoy, Kindly DO Share this session with your friends.
Kun tu exam???
Question 23 the answer is option A please verify ....if rotor rotates at 1500 rpm the relative speed stator field and rotor conductors is zero therefore no induced EMF therefore no circulating current therefore no torque production
Yes you're right
Galti ho jaati hai bhai
This video i found it really helpful and have watched all those mcq videos and shared it w my frnds too. The way you've explained things is amazing and hope your channel grows but one thing i must say you should also provide the PDF in the description too so that we can have it for refrence while practicing aftrwards.
Glad it helped, Kindly DO Share this session with your friends.

@@ElectricalEngineeringMCQs sir bahut lecture ki telegram par PDF nhi hai
Bohot mehnat ki hai sir aapne
Thank you so much Shweta.
Que. 46 It reduces hysteresis and eddy current losses. Option B&C
Core are laminated to minimize eddy current lose.
And high grade silicon steel for hysteresis losses
Super sir in Hindi explanation by you❤
So nice of you
Blocked rotor test is for determine equivalent resistance loss of stator
Excellent sir ur way of teachng
Slip may be defined as rotor copper loss to total rotor power input
Sir your lecture is so valuable..
From now on please present your present your points, we will be noting that down... By the way I don't know Hindi.. But I could able to understand little..

What r you doing man..
🙏🙏🙏
Sir ssc je Electrical paper 1 main numerical Mcq kitne rahte hai.. Out of 100 questions
You may expect 10-15 formula based numericals. Remember this number may vary. I'd suggest you to watch the previous year ssc je question paper which I have uploaded on the channel to have better clarity.
@@ElectricalEngineeringMCQs ok sir thank you 🙏 😊
Ur
Question No 4 ? Pura nhi hua
❤️❤️❤️❤️❤️❤️

Whats the answer of 4th question
5
can anyone explain qno. 23 i didnt understand
Ajay I will discuss this in our session.
I think ans for Q no. 23 is A . Cannot produce induced end and no torque development
4 ques k ans kya h
Kindly Note:- Q.4 Answer is 4Ω i,e. effective rotor resistance in the backward branch of the equivalent circuit will be
R'b=R2/(2-s) ......... -> 7.8/2-0.05= 4Ω. Rest of the explanation is correct.
Q4 ka ans 4 ohm hoga not 2 ohm
Indeed, satya I have recently crosschecked with my reference. Basically it should be Rb'=R2/(2-s) Which will give 4Ω as the answer. Thank you for your keen observation and feedback. For a time being I have omitted the portion of the video and will be corrected in the next upcoming session. Kindly Stay tuned.
