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

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
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.
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
Super sir I think that I will not understand this topic iam fully satisfied . Triangular and square notation is super thank you sir .I liked it so much
I have already made the separate video on the solved problems. Please check that. Here is the link: th-cam.com/video/1tmdiGvvzzw/w-d-xo.html 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)
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.
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.
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!
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?
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
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.
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.
I have already made videos on that. Check these two videos: 1) Two mutually coupled inductors in parallel th-cam.com/video/NacczEJj_iI/w-d-xo.html 2) Three Mutually Coupled Inductors in Parallel th-cam.com/video/BcZew3vcN94/w-d-xo.html
@@ALLABOUTELECTRONICS Thanks for your quick response. This series on magnetically coupled circuits is not outdone by any other provider on this platform and the BJT solved problems playlist was the best 12 hours I ever spent on the internet.
Can you show the series connected inductors also with the magnetic core included? (Even the calculation is possibly correct) Green dots show series connection of L1 and L2, yellow dots the series connection of L1 and L3 and orange dots the series connection of L2 and L3. Maybe if its same magnetic flux it can use just same dots. The dot point the side of the coil where magnetic flux come out. If all the coupling exist or there is flux coupling between 1&3 and 2&3, but not between 1&2. If the magnetic core can have 2 branches also. Flux1 going through l1&l2 and flux2 through l2&l3. I'm not sure if I could be sure without magnetic flux drawing.
Excellent! Thanks! India rules! Greetings from Norway!
Thanks man ❤️
Hell yea. You got that right 🤓😁
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...
@@helloguyswelcometomyvlog same here
ALSO at about 15:16 the different symbols: dot, square, and triangle, REALLY HELPS! I have never seen this notation before! EXCELLENT!
Love this, I have no idea why my professor didn’t connect the dot convention to the physical inductors, this is way more intuitive.
Dot convention starts at 6:34 , the previous are the reasons for its existence
Alaa Hesham how something hold without existence.....?.. so it’s has to be mandatory
Thanks
Thank youu sooooo much for all these videos, they have literally healed and saved me!!!
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
Never saw this so neatly explained. Outstanding work!
got this a day to my exam thank you man
Excellent video
Many lectures failed to teach in this kind of easy and understandable way❤️❤️❤️🙏🙏👍👍
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
very nicely explained.
Friendly advice for learners: watch it at 1x only even if you usually watch at 1.5x or 2x
I liked it at 0.75x
OOO bhaiii kya hi excellent explaination ......thankxx alot bro 🔥🙌🙌🙌🙌
Excellent explanation , greetings from Egypt
explained so well, thank you, sir!
When you write a formula please do not immediately erase it. The full formula is on the screen for literally a single frame
excellent explanation... greetings from Bangladesh
Very very very good sir
From Bangladesh 💕💖
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
difficult concepts are explained in a very easy way...... its been my habit to go through this channel for every difficult concept....
Super easy explanation.❤❤
Fantastic video. Brief and informative. ✌️
Bunch of thanks for the very clear explanation❤🧡
One word outstanding
Very well explained. Thank you sir 😊
Excellent sir. Totally satisfied with this topic. Thank you!

Hi
These are wonderful videos.
I am curious to know what software you are using for drawing the diagrams and writing the equations.
Well done sir. Nicely explained. Thank you.
Excellent explanation and more useful😍
Thank you very much sir. You have explained very nicely.
shouldn't the polarity of V2 at 11:00 be reversed ?

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 ?
Great explanation sir. where to get the notes
You can check the website www.allaboutelectronics.org
Some notes have been updated there. More notes and quiz are provided through the membership.
great explanation sir, thanks.

Great sir thnk u 🙌coz of u all concept r clear it's beneficial for us
gammak thama 👌
Superb video SIR
Thanks for ur cooperation towards "EDUCATION"
Will u keep the link of 3 phase analysis
Re: dots and polarity shown at 10:47
It seems the polarity induced does not agree with the dot arrangement.
ok uncle
thanks nice yideo.......
EXCELLENT THANK YOU SOOOOOMUCH
Excellent😚😚😚😚
Well explained! Subscribed your channel :)
Shouldn't the signs of SELF induced voltages be negative because of Lenz's Law, or am I missing something?
thankyou, it really helpful
Awesome and vibrant explain. Please make video about all topic in Basic Electrical and Basic Electronics. 😢🙏🏼🙏🏼🙏🏼♥️♥️
Nice explanation sir , it helped me a lot
Excellent 👍👌
Please ,solve an example for first state that have two power supply in two side of circuit .thanks

Thank you very much
Can U upload videos of digital gates , circuits , flipflops and binary systems
Yes, In fact I am planning to start a new series of videos on digital electronics. So, definitely you will get the videos on these topics.
Thanks 👍
vidio is good . i want more problems related to this topic
Super video. Can you please derive the proof for parallel mutual Inductance
I have already derived it in the separate video.

Are these examples of conventional current flowing (conventional notation) or electron flow notation?
Conventional current

Just here to see tha square and 🔺 dots... 👍
at 0730 you say same polarity appears across dot but that is source excitation and not the induced one can you clarify?
Thank you sir
You said dot have same polarity but in the case where the two dots are opposite their polarity is also different...plz explain
Can you show the series connected inductors also with the magnetic core included? (Even the calculation is possibly correct)
Green dots show series connection of L1 and L2, yellow dots the series connection of L1 and L3 and orange dots the series connection of L2 and L3.

Is this co efficient of coupling is same for series n parallel
If not derive for parallel
