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.

Why would he get a nobel Prize for being great at teaching? No wonder you don't manage ur classes and come to TH-cam for help!
@@aravindchakrala2429 bro what are you doing here?
Not managing your classes?
@@jeetbiswas8933 yep. 😂
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.
exactly you deaerve nobel prize..definitely....
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 👍
Our teacher didn't even taught AC and DC he directly started showing us AC graphs and all.
One of the leading teacher*
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?
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 🤲⏰😂😂😅
super underrated, deserve more views. thaank you!
Thank you so much for your love and support!

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 🙏
Thank you so much najam academy! ❤
What an amazing explanation 😶😲😲❤️💗
Oh my god very good explanation 👏
Very good lecture. Thanks a lot .
Very nice. Please explain the difference between magnetic induction, magnetic field intensity, magnetic susceptibility permeability
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 💙💙
Honestly very helpful lecture. Thanks :D

Amazing thanks to you I know what ac and dc
Plz make a vdo on strong (acid, electrolyte, base) and weak(acid, electrolyte, base)
And how to identify them...
Sir your explanation is very nice
I also shared this video to my friends
Iam studying for my boards which is on 10 may
So wish me best of luck
Best of luck!!!

Loved it..
Thank you very much sir ..
This video was so helpful!☺
I really impressed sir excellent
Bestteacher
Good teaching
Superb explanation
Thanks
sir, You are always super
Very nice 👍👌I have understood it
@Najam Academy If ac current polarity changes, why don't we get shock when we touch neutral wire.
Thank you very much I understood it very clearly
super sir easy to understand

HIGH VOLTAGE ROCK N ROLL!!! 🤘🎸⚡️
Thank you, I learnt alot
Sir i love your vedios
Great teaching sir🙏
Thanks a lot sir
Thanks sir for the information..
Clear explanation
Bravo Bravo sir best explanation
Bery nice explanation. Always teach with visualising examples and analogies...
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 ?
Plzzz make a full video on Alternating Current chapter!! 🙏🥺
Explained very well
nice teaching sir
excelent explanation !
Thanku sir it helped a lot 🙏
awesome sir
keep it up
tank you best video i ever seen
speed 1.5 and its perfect
Sir one shots bnado class 12 ke chapters pe board ke liye help milegi
It was perfect, very well explain , thank you :)

@@anniebassist1 what you're saying doesn't make any sense. Current is a stream of charged particles, in this case electrons.
There are two theory’s

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,
