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!
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.
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
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 ....
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.
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🇵🇰.
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
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..
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
very practical insightful video on this topic, i am an electrical engineer, another way to say the gnd wire shunts fautl current because it is tied in parallel with the cat or person
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 😅😅😅
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!
Him: The kitty receives a nasty shock. Also him: No animals were hurt in the making of this video. ok but jokes apart. Thanks a lot sir, really helped. However, 1 doubt. In my physics textbook it says Live wire carries current to the device at high voltage, and neutral wire completes circuit by carrying away the electricity. So, could you please tell me if that is correct. (I'm in 8th)
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!
1- live wire or negetive wire 2- netural wire 3-ground wire 4-220 5- is is dangerous because current is constantly flowing through that conductor and if we touch that wire standing on ground the circuit will be made and we will get a shock!!
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
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
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.
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!
The ground pin is longer for another reason too, it opens the live and neutral sockets. If you look at the neutral socket in your picture, you can see it's white on the inside. To stop children sticking things in it.
The ground wire pin is thick because resistance is inversely proportional to the thickness of the conductor, so current will flow through this earth wire instead of metallic body of any appliances :)
indians improved their skills on spoken language, it was below philippines, now it seems above that grade. could well be in first place near future as categorized in second language . the funny thing is USA / UK / AUS are not in this list because of grammatical error, also 70 % less writing skills. this is why we are expertized in writing and learning coding system for machines. goodluck mates
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.
In negative cycle, in which direction the current flows? As we know that current flows from higher to lower potential, then if neutral wire is always maintained at zero then from does the current comes from?
In negative cycle the current (or electrons) simply get "pulled" while in positive it is "pushing". So, the live wire is just pushing and pulling the electrons similar like ebb and flow of the ocean.
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. ❤❤❤❤
It is so easy to understand, Thanks for the video. I have some question,why the voltage of neutral is equal to zero since AC power source is use, it goes forward and back but LIVE is at high voltage while neutral is zero? Is not both should have similar voltage ?
I think this video was very well explained, but I think you missed something regarding the ground wire. While it does go to ground via a grounding rod, most of it goes to the neutral of the transformer, then the hot side and back to the house and trip the breaker on this circuit. The ground wire is connected to the neutral at the electrical panel, but the breaker wouldn't trip if all the ground fault current went to the earth. Another thing is that many even higher power tools and appliances have only a 2 prong plug and it's safe because of double insulation and a plastic case, so anything metal is out of reach. I'm in North America where the positive and negative are 120v relative to the neutral.
This series is so underrated people would rather watch someone who's from an IIT than someone who's actually good at explaining stuff

Same here. Only while teaching my daughter did I come across these beautiful explanation videos and finally got my concept cleared
Not trying to stereotype, but why are Indian people so good at explaining things in a straightforward way.
Awesome .... awesome . ... awesome ..... no words......
Best channel for phy
wow. I have heard and read so many explanations, but yours is just wow. I understood everything at once. Thank you soooo much.
Khan Academy is truly soooo underrated!!! Thank you for saving my life during my exams!!!!!!!!!!
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

The best video on this content I've ever seen.
the best video.....loved it ..i don't write comments but this was just mindblowing .....thanks from bottom of my heart..
This is the best explanation I have ever heard in my life.
love how you explain concepts with simplistic examples to real life. Especially the football one...
That was the best explanation ever
This is the best video I have found in TH-cam that explains the three different wires. Thank you very much!!! for the amazing explanation.
Today I clearly understand live, neutral and earth wire, u r explaining in much better way. God bless 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❤️❤️
never commented on any videos until now... worth the watch!!
As said no cat was harmed in making of this concept 🤣🤣🤣🤣🤣

no words to describe how good and informative this video actually is...ty sir🙏
Thank you sir your contributions can not be forgotten🥰
Waoh.. Simply amazing
Finally...thank you Khan Academy
1- live wire or negetive wire
2- netural wire
3-ground wire
4-220
5- is is dangerous because current is constantly flowing through that conductor and if we touch that wire standing on ground the circuit will be made and we will get a shock!!
Thankyou Sir Mahesh for putting much effort in these videos. Hoping for more electronics-related playlists in the future! :)
the best video ever thank u sir 👏👏👏
By far the best explanation video I’ve ever watched. Although I’m living in NA.
Thank you, its ingenious thank you khan academy
Wow, what a video! Thanks s lot for explaining live, neutral, ground wire. And the poor kitty !

Brilliant explanation. Clear and concise.
It was a "nasty bad day" for the cat. We had to shock her so many times... 😄 Excellent explanation. 👍👍
wowwww... excellent explanation!! highly underrated (as of 2020)
These videos are great
..really good job...thanks
Very good simple way tutoring.The feature and function of earth pin I came to know first time now.thanks a lot.
I've never fallen in love with a Physics video. And now I have after watching this one.
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!
Thank you so much, sir.
I've had problems with this topic and I could've never asked for a better explanation

Good safety feature on some country's plug sockets (not all). More or less universal in the UK
The ground wire pin is thick because resistance is inversely proportional to the thickness of the conductor, so current will flow through this earth wire instead of metallic body of any appliances :)
Wow super easy explaination.

This is such an elaborate yet simplified explanation. Really great! Thank you!!
U r amazing.Sir ur voice is so soothing
i think the ground pin is made thicker also because more surface area = less resistance
why?
