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.
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.
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
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
Most welcome Amit, You are going well by exploring our previous sessions these I sessions I have made with special efforts and is beneficial for all exam. If you could explore our previous sessions in detail trust me you will find 80% of the most important questions with data for your upcoming exams.
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..

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 😊

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

Kun tu exam???
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)
Bhut aacha explanation💯💯💯
Sir aap bahut hi accha padate hai 👌👌❤, aal tuber the best 👍💯👍💯
Thank you so much Brijendra for your kind words. Kindly DO Share this session with your friends,
@@ElectricalEngineeringMCQs sir bahut lecture ki telegram par PDF nhi hai
Super sir in Hindi explanation by you❤
So nice of you
Excellent sir ur way of teachng
Bohot mehnat ki hai sir aapne
Thank you so much Shweta.
Thank you for your valuable video 🙏😊
Thanks a lot sir ji
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
very nice
Thanks
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

Induction motor ki class bahut hi Achcha Laga
Thank you Likewise Kindly DO Watch Top 50 MCQs on Alternator Session.
Slip may be defined as rotor copper loss to total rotor power input
Starting curent of induction motor is 5to 7 time of rated current starter are used for reducing the current nahi to armature jal jayega
Laminated core is used for to remove eddy current loss
Sir this video is very useful for me 🙏 🙏 thanks sir ❤️
D c shunt motor for lathe blower centrifugal pump and conveyor
d.) All of the above

All of the above
Blocked rotor test is for determine equivalent resistance loss of stator
Most helpful vedio....Thank you.
If rotor resistance is equal to rotor resistance at standstill then maximum torque is equal to starting torqua
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..
Slip of 3, phase induction motor is copper loss at roto/total power input to rotor
Good class 👍
Glad you think so! Kindly DO Share.

Sir pls pdf for IM and alternator..
Magnetic locking is called cogging
Ans : D ... Maximum torque depends on voltage(V^2 ), reactance(1/2X) and frequency (sf)
Maximum torque depend on all the above

Sir aap bhout sahi padate ho bus thoda awaz me confidence le aao...
Thank you so much for your kind feedback.
Induction motor me - speed torque curve staright line hoga
Induction motor me torque auto transformer ke current efficiency ka square time ke brabar hota hai
Induction motor run on less than slip less than 00 s
If initial slip in - motor is s its two lead imterchanged then its slip will be 2-s
Agar auto transformer ka 50 percenr tapping hai to - torque square time kam hoga
If resistance in rotor increases then torque will increases but efficiency decreases
