Explained in best way...None can explain like this 👍✌️
Very nice explanation. Thank you sir my all doubts has been cleared 👍👍👍
@Genique education
Respected sir please provide full course of Mathematics and Aptitude for other streams also so that students of all the streams will get benefitted.......this will be a great help 🙏;
Fantastic Sir...
Keep it up
Sir please check the phasor diagram once again.
AMAZING LECTURE
Awsm experience
thank u very much sir....nice coverage in less time
Thank u so much
Ur videos are very beneficial for us
one of the best ....
well explained
Owsm sir
Awsm sir!
Thank you sir
You're just awesome
Check phasor diagram again please. You are not following lenz's law in drawing phasor diagram.
Ya right in previous video also...-N dfive/dt......
Everything is included . Aaplog Jin books ko follow Kar rahe ho due to that getting confused. Better to watch lecture properly or do follow some standard books also okk
Sir in ideal transformer current will be zero when permeability tends to infinity then how flux will produced
You're right but in this case very less amount of current ( i →0) is able to produce sufficient flux...
magnetising current is zero in ideal case because core has high permeability
Sir may opposite convention man ta tha so I am confused, muje samaj nahi a raha is convention me supply voltage ka phesor kaha hoga in phase with e1 or in opposition phase with e1. And I'm this convention how transformer is 180 digree phase shift device as we usually say
thank you sir,
Sir please synchronous machine ka gate questions dalo .
Sir voltage ko badane ya kam karne se flux par kya effect aata hai
sir actually i have a dought that if the reluctance is 0, thn it is also 0 for the 2nd coil also, than why the current flowing in coil 2 is not 0
Sir how e1&e2 is leading Φ by 90 degree
Anant mishra phasor is wrong I guess.
sir please make a lecture on how to draw a phasor diagram
Sir agar i2 and i2 ' same phase main hain to dono ka flux oppos kaise karega
Sir why we call Transformer as a phase shifting device?? If e1 and e2 are in same phase
e1 and e2 should be in same phase instead they are out of phase from supply voltage.
Sandy Paul e1 and e2 should be in same phase, but they should be in 180°out of phase of supply voltage
Sir why Io is 0 in this case as you have taken permeability finite.?????
Sir, In loaded condition of ideal transformer , Magnetizing current will be Zero or Not
At 7:48 sir, why "io" is zero when permeability tends to infinity
As permeability tend to infinity, opposition to flow of flux that is reluctance is zero,as R=0,we know flux=mmf/reluctance,mmf=NI,put value of mmf in above,flux=NI/R,as transformer is constant flux device,we want constant flux in core,that is its peak value of flux is constant,as R is tending to zero then flux is infinite as1/0=infinity,but we want constant flux,so I must tending to zero ,as we can't change value of N.,that is required of magnetizing current ,Im for the flow of flux is zero..hope u get
supply is connected when the secondary on load condition without supply on no load condition then what is about the no load current.please give me reply.
pls reply sir
why the load is delivering in nature?
But sir you say in lecture 2 (18.05) that flux is a time varying....aur Abhi constant kaise ho gya.
Rajnikant Sinha wahi bhi time varying hi hai core ka flux always constant hota hai
flux ka amplitude constant rahega. Yhan pe sab values time varying hai baat unke amplitude ki hi ho rhi hai..
Acchaa ac voltage hai 220 volt mere ghar me
Constant h ya nhi Usi tarah Φ in transformer core is constant but is altarnativie ( alternative means changing its magnitude wrt time periodically)
@@twinkle6884 As we know that in practical x-mer..for (lagging pf,induced emf is less than applied voltage that is( ev)... since flux is proportional to emf.... therefore. Flux reduces in lagging pf and flux increases in leading pf...{€=4.44Nf*Flux}. flux proportional to €..
I am not talking about only core flux..i am talking about overall flux.
Sir it Bale me bhi Kam ayega Kya..
Everything is very helpful except phasor diagram , there is some mistake.
no there is not he is saying that it is an ideal transformer and and losses are neglected therefore no load current will be equal to the magnetizing current and what you are thinking is the case of an practical transformer
Ok check it in any book
Yes u r right
Phasor diagram is wrong
When Sunil Shetty teaches you😂
Sir, can u provide pdfs of your videos ?
Sir I think phasor diagram is wrong
sir if premeability is finite(very large ) and driven at no load then i2 will be zero or not ??
No, There will be no i2 as its under no load
10:30 load lagging nature ka hai?? Matlab??
Assume Kiya hai Bhai
24.09 sir i1/i2=1/a under no load is not true
why sir?
i2=0 under no load
Ab nehi bachega koy question of machine
Sir, i1 and i2 should be out of phase
Yes
Sir aap phaser diagram me supply voltage ko show q nahi kar rahe h
supply voltage is equal to the primary induced emf as there is no losses
supply voltage is out of phase of induced emf both e1 and e2
vishal sharma supply voltage is equal to primary induced emf, but e1 should be in opposite phase right. In case of amplifiers we also studied that if we use transformer for impedance matching we get outpost 180° out of phase
Sir aapne and nahi kiya ki current zero kyo hogi
Phasor is wrong.
(Im why 0
Sir your phasor diag is completely wrong !
It's absolutely right dear. Better to refer some standard book rather than bhimbhra okk
Sir which books do u refer ?
Plz give me your suggestions
Sir plz don't waste more time on theory do more problems..humble request.
yes......
Sahi kaha... Theory me time west ho raha he..
@@Bookeda Pankaj shukla sir kaho brother.. or ha Gate me kam time bacha he is liye time west lag raha he kyu ke GATE me theory to aaye gi nahi..baki Sir to best padhate he..
You are dealing machine first thing and without knowing theory you can not think about problem solving dear.
bhaisaab log jinko lag raha he theory jayada ho raha kuch kam ho raha he...please behave yourself...you are talking to god of electrical machine...he knows everything about gate better than you..so dont frustrate...ye machine he beta direct formula based question nhi aate hen..fully concept based only jo sir ki awesome theory se hi clear hoga..good luck.
Like kar diya karo kanjusso isme kon sa paise lg rahe h
Thank u sir
Thank u sir
