Dot Convention in Magnetically Coupled Circuits

[@BentHestad]

Excellent! Thanks! India rules! Greetings from Norway!

[@ANGRYONEFF]

Thanks man ❤️

[@godwincornelius201]

Hell yea. You got that right 🤓😁

[@helloguyswelcometomyvlog]

For the last 10 days, I was struggling with this topic. But because of you in just 15 min my whole topic is clear. Thank you sir...

[@whyuask1786]

Love this, I have no idea why my professor didn’t connect the dot convention to the physical inductors, this is way more intuitive.

[@dalenassar9152]

ALSO at about 15:16 the different symbols: dot, square, and triangle, REALLY HELPS! I have never seen this notation before! EXCELLENT!

[@TrueDetectivePikachu]

Really great video! It really helped me understand dot convention. Pauses on certain parts of a sentence are done in a kinda weird way, but aside that the explanation really nailed it! Really wish books went straight to the point like this vid

[@SebastianRamirez-jr6bs]

Never saw this so neatly explained. Outstanding work!

[@ganeshracha5552]

Excellent video Many lectures failed to teach in this kind of easy and understandable way❤️❤️❤️🙏🙏👍👍

[@jatinsolanki1130]

Great explanation sir.I was not able to understand what was explained in our book but you made it very easy and simple to understand.Thanks a lot

[@vkrs3315]

very nicely explained. Friendly advice for learners: watch it at 1x only even if you usually watch at 1.5x or 2x

[@Festus2022]

I liked it at 0.75x

[@edt.l.892]

got this a day to my exam thank you man

[@rahmankhan295]

OOO bhaiii kya hi excellent explaination ......thankxx alot bro 🔥🙌🙌🙌🙌

[@deekshithanantha8114]

My teacher takes screen shot of this video and tries to teach using ur videos only hence i wud rather watch these videos then listen to her class

[@harshkumarsinha1865]

One word outstanding

[@sheiktajwar7227]

Very very very good sir From Bangladesh 💕💖

[@alaahesham250]

Dot convention starts at 6:34 , the previous are the reasons for its existence

[@basics7930]

Alaa Hesham how something hold without existence.....?.. so it’s has to be mandatory

[@ANGRYONEFF]

Thanks

[@spokitive]

Excellent explanation , greetings from Egypt

difficult concepts are explained in a very easy way...... its been my habit to go through this channel for every difficult concept....

[@aritrobanerjee8024]

You earned a new sub! I would really appreciate if you made a video on deriving the expressions for self inductances. Thank man :)

[@ALLABOUTELECTRONICS]

Dear Aritro, I have already made a video on self-inductance and mutual inductance. You may check that.I am giving a link below for it. kzbin.info/www/bejne/nqC3eqGKgM6dZtE

[@sailikhitha79]

Please solve few problems for complex circuits in this topic I liked the video very much

[@ALLABOUTELECTRONICS]

I have already made the separate video on the solved problems. Please check that. Here is the link: kzbin.info/www/bejne/Z6XQlZx9q9utsNk And in the description of the video, I had given the link for more problems. Apart from that, if you go to the community tab of the channel you will also find a few Quiz on this topic. (You need to scroll down a bit to find that)

[@hanokmacha00]

Excellent explanation and more useful😍

[@PaidiGeetesh]

great video,, thanks

[@johndus1193]

Quick question on dot convention please? What if on the first coil, the current is pointing towards the right direction and the voltage is - up + down AND on the second coil, the current is also facing the right direction and the voltage is + up - down AND both coils are dotted at the top. What is V1 and V2 here

[@samsaikia5949]

I finally understood.... thanks man ❤️

[@masudraihan973]

Really helpful, Go ahead and create such kind of excellent video. Best wishes

[@PriyaSingh-gt9xm]

Great sir thnk u 🙌coz of u all concept r clear it's beneficial for us

[@shawaizhaider3978]

Shouldn't the signs of SELF induced voltages be negative because of Lenz's Law, or am I missing something?

[@pbeee2417]

Thank you sir

[@zackm5693]

Amazing video!

[@NumberZeroMusic]

Thank you very much

[@gamingelgato]

thankyou, it really helpful

[@yoursbadal]

Well explained! Subscribed your channel :)

[@saisuhas8217]

Nice explanation sir , it helped me a lot

[@philipdavidroy2558]

Amazing video, really needed this.

[@GSGamersince1999]

Thanks 👍

[@KiranKumar-pr6pj]

vidio is good . i want more problems related to this topic

[@basics7930]

Great

[@reazuddinbhuiyan2210]

You are doing something which is disturbing to the viewers... writing an expression and removing it immediately! areeh vai we the beginners need some time to take inside our brain so why dont you keep the expression in the frame for couple of more seconds? may be you can use the frame space more efficienly. like writting more in one frame.

[@The321twilight]

Very good lecture sir, thank you!

[@udayaprabhub7481]

Nice video! Thanks man!

[@neatvfx]

I have a little doubt here. According to faraday and Lenz law, the self induced EMF is "minus L(di/dt)".Why use neglect the Minus sign of the lenz law? if u see this, plz response.

[@shlimjim23]

A long time later but I also agree. I think it’s the wrong way around here. Maybe I’m wrong, but in the example when the flux from both coils is in the same direction, increasing current I1 would increase the total flux through coil 2, thus coil 2 would produce an emf to undo this change, i.e. a negative emf, thereby generating a downward flux. The opposite happens for the second example.

[@priya03_94]

Superb video SIR

[@dalenassar9152]

GREAT VIDEO, IN FACT, THE BEST, BY FAR, I'VE SEEN!!! Also, your offer at about timestamp 14:55 is "YES", I would "LOVE" to see the derivation for the series "and" parallel connections!

[@ALLABOUTELECTRONICS]

Thanks. I have already made video for the derivation. Please check the cards or the description for more info.

[@electricalfarmer8876]

GOOD

[@rekhatarunyab5998]

Excellent😚😚😚😚

[@jspencerg]

Re: dots and polarity shown at 10:47 It seems the polarity induced does not agree with the dot arrangement.

[@lathikawathsara2649]

gammak thama 👌

[@SaikatSaha-ni2ep]

Bring much video like electromagnetism, ac circuit.

[@user-nv3sb5hr2f]

thanks

[@manoharachuthanarayana2900]

Excellent 👍👌

[@suryakameswararaopatruni8669]

student friendly video sir

[@sarathsaipeteti6029]

Owesome thank you

[@mnada72]

shouldn't the polarity of V2 at 11:00 be reversed ?

[@anujkondhalkar9776]

Sir well done. Good explanation. Thanks a lot.

[@anujkondhalkar9776]

Sir , I've completed engineering in electronics and I'm preparing for gate 2018. I'm scared . Lack of knowledge and very less time. How can I clear the gate. I want to do M.tech from IIT. It is my biggest wish.

[@ALLABOUTELECTRONICS]

Hey Anuj. I hope you are already preparing for the GATE and not starting it just now. See, syllabus for the GATE is quite lengthy. There are so many things. But working smartly it can be tackled. Just focus on your strengths, the subjects you are very confident about and the subjects which are relatively easy. Well, here I am not going to say which subjects are easy because it depends on person to person. And try to solve the previous year's GATE papers. If you need any other help then feel free to ask.

[@anujkondhalkar9776]

Thank You So much sir. Definitely sir , if I face difficulty I will as you.

[@indraiahlingampalli470]

I need your help in knowing the types, details about resistance, capacitance,inductence items.

[@ALLABOUTELECTRONICS]

I have already made the videos on it. Please check the playlist on basics of electronics on the playlist page of the channel. You will get all the videos. If you didn't find then do let me know here. I will send you the seperate link.

[@sobhanadatta1161]

Hey it would be really nice if you tell me which video is next as I am really confused.also the last part of this video ended abruptly without showing the relation between the three

[@aryanbarnwal5645]

Great explanation sir. where to get the notes

[@ALLABOUTELECTRONICS]

You can check the website www.allaboutelectronics.org Some notes have been updated there. More notes and quiz are provided through the membership.

[@ramuperala4922]

Will u keep the link of 3 phase analysis

[@Noobgamming.]

Derivaton for parallel coupled Leq?

[@Festus2022]

Great video, but I am confused about the basic setup with the 2 windings around the same core. What is this supposed to be? In a typical transformer there would be no current source feeding the secondary winding The coils are not in series, So what exactly is this setup?

[@anoohyanagula1342]

👍 sir. I need derivation of equivalent inductances in all 4 cases

[@ALLABOUTELECTRONICS]

The seperate video is already made for the same. Please check the playlist of magnetically coupled circuit on the channel for more info. If you go through that playlist, all your doubts will get cleared.

[@UdayKumar-yp4vh]

Thanks sir

[@waelsadek81]

15:30 Why using square and triangle, the dot will either has to be on one end or the other for coil 3 as there are only two ways to wind any coil ?

[@indraiahlingampalli470]

Superb Can you please explain about coefficient of coupling

[@ALLABOUTELECTRONICS]

I have discussed it in the video of self inductance and mutual inductance. Please check that video on the channel page. Or even you can get it on the playlist page under magnetically coupled circuit

[@waelsadek81]

Shouldn't self inductance be negative 3:08 ?

[@sudarsanareddy.k2337]

TQ

[@indianancientscience6253]

Yuuu luuuluu ! Greeting from yuganda

[@ishraquearshad1621]

Where to put dots??? Criteria??

[@noweare1]

I always took the dots to mean that the phase of the voltage is the same at the dots since current direction is not normally shown on a schematic.

[@noweare1]

Your math backs that up. When ever I 1 enters the dot and I2 exits the dot the Mutual Inductance has a negative sign in front.

[@SaurabhKumar-gc1ko]

at 0730 you say same polarity appears across dot but that is source excitation and not the induced one can you clarify?
