Sir your explanation is awesome.. i really impressed to learn more about physics .. we are really blessed to have a teacher like you.. *Single phase and Three phase difference* upload a video for that . It will help me to learn good..
Everything was perfect 👌 but must hav examples as well 😐.If possible Plz make a video on categorically examples of AC & DC current with Electric devices,motors and machines name 😊. Thnks for this one 🙏
2:43 He has said that the wheel has done work, even when it came back to it's original position in the 2nd case. But work = force * displacement and here as the wheel came back to it's original position the displacement (distance between initial and final positions) is equal to 0, making the work = 0, I'd like someone to correct me if i am wrong.
Sir , one question that troubles a lot of people , if current alternates why do we distinguish the 2 cables (for a single phase ) as hot wire and neutral . if it alternates then shouldn't for the first half cycle the brown wire (L) to be the hot one and blue wire (N) to be the neutral and for the second half cycle the brown wire to be the neutral one and blue wire to be the hot one ?
According to ac theory, current has to flow through both wires alternately but we find live wire and neutral wire in domestic ac applications...does that mean the electrons come through live wire and return through neutral like dc current...Please explain...
Easy to understand however, it's my understanding that current always flows from the negative terminal. This illustration showed the current flowing from the positive terminal.
im not sure, but i think that conventional current flows from the positive terminal to the negative. notice that i said conventional current. if im not mistaken, in the past everybody thought that the current flowed from positive to negative, but long story short, now we know that are the electrons who go from the negative pole to the positive. sooo the real current indeed flows from negative to positive, but the conventional current, the one that we usually see represented on diagrams, flows as shown in the figure (positive to negative terminal)
There are two theory’s Conventional current and electron current, Conventional was developed off of Benjamin franklins idea that current flows from positive to negative, However J. J thomson (correct me If I’m wrong), discovered that this was not so, but rather that electrons were a negative charge and were draw towards the positive charge, Thus concluded that the electron would flow from negative to positive. And so current is known to flow in the opposite direction of the electrons, However as a side note, the conventional theory is still being taught to erase confusion and simplify learning. As most of the world uses conventional theory. Furthermore, if we look at the bigger picture, scientists/ physicist, may say that it does not matter what way the current flows as this does not alter the values in any related formula. I hope this helped.
Thank youuuuuu soooooooo much sir this ques is breaking my mind for so many day that how AC current flows You had cleared my doubt thank you so much sir 😍😘😘😍😍😘😍😘😘😍😍😘😍😘 Also sir I am also thinking that what is then frequency for That also you had cleared 😘😍😍😘😍😰😍😘😍😘😍😘😍😘😘😍😘😍😘😍 Sir infinite times thank you 😘🤩😘🤩😘🤩😘😍😘😍😘😍😘😍😘😘😍😍😘😍😘
Bulb is glowing, Electric current is flowing, and your teaching is MIND BLOWING!!!

Why would he get a nobel Prize for being great at teaching? No wonder you don't manage ur classes and come to UA-cam for help!
@@aravindchakrala2429 bro what are you doing here?
Not managing your classes?
@@jeetbiswas8933 yep. 😂
Very simple and basic teaching. Easy to understand this video for a life time. Thank you.
People make difficult things on easy way but you are not 👍
Ah this wasn't even that hard I wish people explained things as simply as this. Really helpful😎
Thank you so much!!!
🙏🙏🙏🙏🙏
True ❤thanks bhai
After all this time of trying to understand AC and DC, I finally get to understand thanks so much once again.
Sir your explanation is awesome.. i really impressed to learn more about physics .. we are really blessed to have a teacher like you..
*Single phase and Three phase difference* upload a video for that . It will help me to learn good..
Sleep during class 😪😴🛌wake up during exams 🤲⏰😂😂😅
This presentation is awesommmme, i really liked ittttt, didnt youuuu?
Yes I diiiiiid!
Saaaaaaamme
It is annoyinggggggg
I did
I watched in 1.5 speeeeed. Wat abt yuuuu?
Our teacher didn't even taught AC and DC he directly started showing us AC graphs and all.
Satisfying video 😍 presentation was first class and your accent is also reliable😂❤️
It's just 4 days to my entrance test and I hadn't got this topic yet. Thank you Najam Academy!
Which entrance are u giving???

Thank you. This is a very useful video. Like studying from school.
super underrated, deserve more views. thaank you!
Thank you so much for your love and support!
God bless you and your whole family!!!
🙏🙏🙏🙏🙏
No 😔
Your presentation and explanation using everyday life examples is excellent & easy to understand electric concepts.
Wow finally someone breaks this for me very easily. Thank you
One of the leading teacher*
Thank you so much for.your video. I have been struggling with this subject and you helped me with your marvelous explanation
Your teaching is like a Direct current, flows directly into a mind ❤️
listen at 1.25x
thank you for this video sir! very informative and easy to grasp. more power
Welcome!!!
🙏🙏🙏🙏❤❤❤❤
sir thank you sooooooooo much u helped me a lot to understand this i was looking for dc/ac motors and i found this it helps tysm 💙💙
Always a Indian guy out there who will break down something you are struggling with.
6:36 but what is its cause as It's reversing it's direction
Everything was perfect 👌 but must hav examples as well 😐.If possible Plz make a video on categorically examples of AC & DC current with Electric devices,motors and machines name 😊. Thnks for this one 🙏
Bahut khoob 😇!!! What a explanation !!! All small main points covered. Keep it up in all chapters. 😃😀🤓🤓🤓
THANK YOU NICELY EXPLAINED
Fantastic 👍,, I wll never going to forget it again❤️
Infact, this video is termed one of the best. So explanatory, I love it so much
This is fantabulous, Thanks for helping,,,lots of blessings and love
Great yar...
Clear my concepts
Very beautifully explained. Appreciable 👍🏻👍🏻
best teaching ever known..
Very nice. Please explain the difference between magnetic induction, magnetic field intensity, magnetic susceptibility permeability
speed 1.5 and its perfect
After your class, electro physics seems as easy as a romantic literature. Huge respect Sir!
I understand more than 90 percent
Iiked your explanation sir
You are clearly explained. Like that please explain some basics for BE ece
Sir your teaching skills are amazing I like it la
world best explanation sir. 100 claps for uu..👏👏👏💯💯💯👍
Sir soon give us information about Walt and watt ❤❤❤❤❤❤ thanks
Plz make a vdo on strong (acid, electrolyte, base) and weak(acid, electrolyte, base)
And how to identify them...
It was perfect, very well explain , thank you :)
Honestly very helpful lecture. Thanks :D
Thank you very much I understood it very clearly
Nicely explained thank you so much!
One of the best lectures !!
Keep it up.
Thanks a lot sir
Amazing thanks to you I know what ac and dc
Thank you so much najam academy! ❤
@Najam Academy If ac current polarity changes, why don't we get shock when we touch neutral wire.
The low note at the end of the sentence is ama-zingggggg
Yes. U deserve noble man!
What an amazing explanation 😶😲😲❤️💗
Bery nice explanation. Always teach with visualising examples and analogies...
Amazing teaching sir amazing teacher would you😊😊😊😮😮😮❤❤❤
Loved it..
Thank you very much sir ..
Very good lecture. Thanks a lot .
This video was so helpful!☺
Exclent explanations,najam academy.......❤❤❤❤❤
Thank you, I learnt alot
Kaash school mein bhi Aise teachers hote
Tq so much 🙏🙏
Sir one point confuse me that in d.c electron does not flow back but in A.c it moves back while the electron is same ?
Thanks sir for the information..
