[@kdutta6951]

Very interesting question. The ans is option C. Plz explain

[@priyaranjanmallick8362]

You have already answered this in a dedicated video Sir . Anyways , my comments over thick copper bars in squirrel cage rotor : SKIN EFFECT may please be reviewed & acknowledged Sir as required .

[@ElectricalTalks]

I understand your point of view. For you, this concept is easy to understand but think about those who are new to this topic. For them this may be helpful.

[@arunkumarbais530]

Excellent knowledge

[@ElectricalTalks]

Many many thanks

[@meermasum4150]

Please describe the equivalent circuit of the Transformer.

[@buddha1529]

Thanks nice video 👌

[@ee_108_ashish5]

Option B is correct

[@sonam_tangard_03]

Very nice

[@mukundjoshi3229]

Very nice.

[@Sam07515]

Changing from star to delta by triple pole double throw switch . After achieving 80% speed .

[@rajeshsaket910]

Thankyou sir

[@ElectricalTalks]

Welcome

[@yogeshbaraik8163]

In star connection line current is equal to phase current , and motor is first connnected in star hence i think option I1=I2. ( if winding of dol motor is in star)
And I2=I1/√3 ( if winding of dol motor is in delta).
Kindly clear me sir

[@arghyabhandari3194]

If any motor run star how much current will draw the same

[@dashok4749]

Brother at the time of starting rotor is at stand still then how the induced voltage or back emf is zero during starting?

[@ElectricalTalks]

Its the induced emf at stator winding due to rotor mmf. Just think about the rotor current & mmf at the time of starting.

[@sohagmostofa5674]

It was great explanation.
Ans. =C

[@nileshnaik9518]

Thanx

[@fanalca]

In 04:59 how that vector has come to cos60
It should be cos 120 know?

[@HEERASINGH-vl1mr]

Option B

[@mahender608]

Answer is "C"... √3 times decrease

[@Chemoholic_Z]

Wow

[@Odiatechnicslexam]

Starting current in without starter 3 times high that's the answer

[@rajatakumarkabi9314]

Option b sir

[@atulkumarupd]

Ans is c

[@rintumondal6509]

Lekin sir jab motor star may chalta hai tab motor yada current leta hai

[@anjaniroy8245]

If I always operate motor in star connection than what happened??

[@rajeshpatra8347]

B

[@TheDhananjay98]

option b

[@RAVINDERKUMAR-ig1vg]

C is answer

[@prabhatsingh5377]

Obtion B

[@firenice5989]

Opn B sir

[@arijitdey2944]

Are you bengali sir?

How to do watt meater calculation

[@shreeradhe2802]

Koi bataye ki timer me 24 sec set hai ,, to 24 sec tak star me current constant current 2,3 times rehta hai.. ya 15, 16 sec bad wah FLC me aa jata hai..
