Live wire, neutral & ground (earth wire) - Domestic circuits (part 1) | Physics | Khan Academy
Вставка
- Опубліковано 25 лип 2024
- The live wire of domestic circuits is usually red and is at high voltage. The neutral wire is black and has voltage close to that of the ground. The potential difference between these two wires in India is about 220 V. The earth or ground wire provides safety against faults and current leaks. Earth pin is longer to ensure earth connection happens first while connecting and last while disconnecting any devices.

I thought I hated physics but honestly I guess I just hate how they teach this in school and how we have to just "memorize" the answers only. Your video was so good and well made. Honestly helped me out big time, not just academically but to finally relate physics with daily life. Physics is so important, it sucks the way its taught, I never had this much fun studying physics ever. Thanks you so much! Keep doing it, you'll be helping so many people in the future!
This series is so underrated people would rather watch someone who's from an IIT than someone who's actually good at explaining stuff

Hii , I'm a Scientist of ISRO
Exactly teaching is a different skill A teacher doesn't necessarily have to be a topper and a topper doesn't necessarily have to be a teacher

I'm 50, and I finally understand this better now. I had a misconception about AC and the neutral wire. I think many of us do after learning DC circuits. You are a very good teacher. Ty.
wow. I have heard and read so many explanations, but yours is just wow. I understood everything at once. Thank you soooo much.
This was so great. I had difficulty in understanding this part, so our school teacher gave us this video, and now it is crystal clear to me in one go. Thank you sir
Not trying to stereotype, but why are Indian people so good at explaining things in a straightforward way.
Khan Academy is truly soooo underrated!!! Thank you for saving my life during my exams!!!!!!!!!!
thank you so much! i love how you explain concepts with simplistic examples to real life because it really stays with me and makes it so much easier to understand. keep it up! :D
Fr!
Your voice, your confidence, your way of teaching, it is full of enthusiasm without any doubts. Amazing, fabulous, and yes, Thank YOU
I must say, this is the best explanation. I hardly comment on videos, but this is just wow👏. That football thing was veryyy good👍. Thanks from the other side of border🇵🇰.
Sir! I can't tell how much I appreciate this video, I had a confusion from a long time about 3-4 months ago that had been disturbing me and there wasn't a better explanation in the world, just the first part of this video made me so happy. If I had been old and responsible enough to donate, you would have been one of the receivers. I feel obliged. "Feels illegal to not pay for this luxury level education". Thank you.
Thanks for the help! I picked up what I was lacking in understanding about this type of current! Explaining how too but then elaborating on the why is awesome!
Thankyou Sir Mahesh for putting much effort in these videos. Hoping for more electronics-related playlists in the future! :)
love how you explain concepts with simplistic examples to real life. Especially the football one...
My god , i have done masters in physics , everytime teachers explained this stuff i would get nothing , today i have understood this and can explain to others .......👍 thank you man ....
Great explanation. The demonstration, the example, the case taken, everything was on point. Thank you.
It was everything I needed to know. Curiosity quenched just like that!
This is such an elaborate yet simplified explanation. Really great! Thank you!!
That was the best explanation ever
Great video! It was good that you explained the effects of voltage differentials to determine the current flow direction and hence how the direction changes, without needing to use technical terms.
Watched many many videos explaining this and you did the best! So thorough!
This is the best video I have found in UA-cam that explains the three different wires. Thank you very much!!! for the amazing explanation.
Class 10 AAJAO COMMENT PADNE
😂🤣
What's padne 😂
The best video on this content I've ever seen.
Thank you khan academy for saving my cat 🫡. But this was very good explanation about different wires.
Beautiful, thank you sir!!!!
Thank you so so so much, sir. I've watched many videos about understanding the electricity for beginners and I can say they are really good at it in terms of their approach or formulas, but still I was so confused some terms or understanding them. You are now very helpful to me about this issue by explaining and depicting these stuffs magnificiently. So again I am thankful to you, sir.
Easily the best video Ive found yet explaining how earthing works.....
Thanks for making it super easy to understand. Superb!
Super sir... Finally understood after so many years... Clear concept explanations must be given like this sir.. This is lacking in Indian education of memorising..
Today I clearly understand live, neutral and earth wire, u r explaining in much better way. God bless you
Thank you so much! It's pretty confusing online when u read tje ground wire is connected to the ground and the metallic appliances but get no context. This is awesome!
this is such a good explanation. Thank you!
splendid explanation sir...respect for u
All of the videos are so good. Thankyou!
explained so simple words. thanks a lot

Explained in a best way thank you ❤️
Man, this is why my Mac has been giving me a shock too every time it's on charge. Very interesting and very well explained!
You have provided an excellent and simple explanation of mains wiring. Thank you!
One of the best explaination i have experienced...
Great way of explaination I have ever seen...thanku....
Soooooo clear and catchy explanation.......Thank you a hundred times
Very very well done, thank you!
You answered all the questions I wanted to know for looooong time thank you ✌
Beautiful explanation and superb use of language 👌
thanks man , I was struggling to understand what is a neutral wire . I mean if the current alternates , both the wires should be the same right ? . the football explanation was outstanding
what an amazing, superb, fantastic,excellent,mind blowing explaination. i really loved it and thank u so much. i had to explain about the three wires in my school activity and after watching this i gave an superb and dense info about the three wires. thx to u
I'm someone with zero knowledge about this stuff. Last week, my friend explained this to me, and now I finally learnt it using this video as a reference 😅😅😅
simple explanation..thank you 👍
Thank you so much, sir.
I've had problems with this topic and I could've never asked for a better explanation

Thankyou sir you cleared all my doubts 🙏🙏🙏
Perfect explaination man. Appreciated
This is the best explanation I have ever heard in my life.
WTF dude I would pay to watch this. So simple yet so practical. I finally understood what is the significance of live , ground and neutral wire in our plug points and also why it is connected
Wow, what a video! Thanks s lot for explaining live, neutral, ground wire. And the poor kitty !
Great video, very clear explanation
Awesome....clear all confusion...
These videos are great
..really good job...thanks
Great sir! Thank you.
i am in 12th finaly found what I've been looking for years...noone told that live wire changes its potential...now i got how is it ac in home❤️❤️
You're Just Excellent Man❤❤❤
Amazed me!!!😺💚

It was really superb.. Thanks
Wow dude, your explanations with simple real life examples and analogies are so easy to understand. Thanks for clearing my concepts!! U r a hero!!
Thanks for uploading this video,It realy helped a lot to me to understand this concept.Nice Explanation.
25 years of education failed to teach me this. I could have opted for Physics had the teachers been less skewed. Anyways, thanks for this beautiful video.
Marvellous 👏👏
I really like your explanation bro🎉🎉
Amazing explanation 😄😄 thank u very much sir 👏
Excellent explanation.
If a got any doubts, you clear them even before start to think.
I never liked any physics video. The first time I put a like for a physics video.
❤❤❤❤
Superb explanation. Instantly subscribed 🔥🔥💎💎
As said no cat was harmed in making of this concept 🤣🤣🤣🤣🤣

Thank-you so much for your clear explanation. You are a very good teacher, even making the suggestion that we go and explain this now to someone else as this is itself a recognised means of effective learning. Thank-you again.
fantastic video, thank you sir
