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
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
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!

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. ruclips.net/video/hoTInTKij0o/видео.html
I have already made the separate video on the solved problems. Please check that. Here is the link: ruclips.net/video/1tmdiGvvzzw/видео.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.
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
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?
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 know my question is a bit idiotic, but don't currents have to first enter the dots to leave it ... I mean if a current doesn't enter a dot in the first place, how will it leave the dot?? At 8:36 u said that current are leaving the dot at the same time ... But current enter bhi toh ho rha h! I feel like the currents are simultaneously entering and leaving the coil . How to determine whether it's actually leaving or entering?? Please clear my misunderstanding!!🙏🙏🙏
The first thing, dot convention represents how winding has been wound around the core and how flux is generated in the core. So, when we say current is entering or leaving the dot at the same time, it means that in both widings flux is aiding to each other. And when we say in one coil current is entering and in another coil current is leaving, it means that flux is cancelling each other. Now, let's come to your doubt.Now when we apply the voltage to the coil then current will start flowing through that coil, depending upon the polarity of the voltage. And current will enter the coil from the positive terminal of the coil. Now, if dot is on that entering point of the coil, then it is called current is entering the dot and if dot is on the other side of the coil then current will see that dot while leaving the coil. and it is called current is leaving the dot. I hope it will clear your doubt. If you still have any confusion then do let me know here.
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.
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

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.
Thank youu sooooo much for all these videos, they have literally healed and saved me!!!
Never saw this so neatly explained. Outstanding work!
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
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
Excellent video
Many lectures failed to teach in this kind of easy and understandable way❤️❤️❤️🙏🙏👍👍
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
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

CLEAR AND CONCISE! THANK YOU!
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 ?
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.

Thanks for ur cooperation towards "EDUCATION"
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
Re: dots and polarity shown at 10:47
It seems the polarity induced does not agree with the dot arrangement.
Great explanation.
you are a gift from God how much you helped me man thank you
Shouldn't the signs of SELF induced voltages be negative because of Lenz's Law, or am I missing something?
Hi
These are wonderful videos.
I am curious to know what software you are using for drawing the diagrams and writing the equations.
shouldn't the polarity of V2 at 11:00 be reversed ?
Thank you for this lesson
got all... great explanation.. thank you..

Can you please explain about coefficient of coupling
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
Nice video! Thanks man!
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.
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.
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.
at 0730 you say same polarity appears across dot but that is source excitation and not the induced one can you clarify?
Are these examples of conventional current flowing (conventional notation) or electron flow notation?
Conventional current
