Hlo, Sir it's 2022 and still ur videos are amazing, and full of concepts, these videos are helping me a lot. Salute to Ram sir 😇. Plz Khan Academy bring him back, there are a lot of students these days, who needs ur valuable techings. And ur videos will definitely be the best. Thanks 👍
Sir i have a doubt that As in metals electron are free.....means one or more e- leave their atom and just rome....so this means due to loss of e- atons of that metal should be an ion(most cases) always ???? True or not
👏👏👏👏It's the best way to teach physics,thankyou so much sir, now this topic is so easy to understand for me........thankyou sir thankyou so much sir........☺️☺️☺️keep it up sir.......🖕🖕🖕🖕
I have one doubt. when water flow below the naro place of the tank. Who it is dffected? I think it is full free at this place and gravitational force directed acts on it. Please do clear my doubt🤔🤔🤔
Sir but why we use that convention only and yahi thodehi ek wajah hai current to high potential se low potential hi jata hai waise unhone sahi bola tha.
@🗿moai🗿 since electric field is from higher potential to lower and so electrons experiences force opposite to electric field that's why electrons move from lower potential to higher this causes flow of electrons!
@🗿moai🗿 first of all potential energy +kinetic energy is conserved and when electrons flows it experiences resistance through kernels (fixed atoms) that's why they loose their kinetic energy and again they gain it! Here there is no point of potential energy!
Sir, if direction of electric current and flow of electrons both are same then why we are following wrong conversation that direction of electric current is just opposite of flow of electrons...it should be change..we should not follow wrong path
if we understand deeper then flow of current is not exactly because of flow of electron, it is because of empty spaces left by valence electrons, so the direction of holes left behind (or flowing) is opposite to the direction of electron flowing which is the direction of current too.
Direct agar battery ke do terminal connect karo ge to short circuit ho jaye ga, kyun ki electric charges ko flow karne mai koi rukawat nhi ayegi aur iski wajah se heat boht zyada produce hoti hai. Resistance lagane se charges araam se chalti hai jis se circuit mai koi problem nhi aati. Har ek wire ki kuch na kuch resistance hoti hai, resistance ka symbol thoda weird sa hai, isliye saari wire ki resistance ek resistance symbol se show ki jaati hai.
Sir uh promised to provide both chem and bio videos whn u ppl crossed 1k subs....BUT THEN we are waiting sir................................................. It's been a month and u hv 73subs more but whn are uh going to upload sir...we are waiting AND PLZZZ START WID CHEM VIDEOS FRST Those who want hit like
Why we still follow that electricity move from positive terminal to negative terminal but in reality electrons move from negative terminal to the positive terminal?
If the question comes about defination of ohm's law u should wright: In an electrical circuit the voltage(potential diff.) is directly proportional to the current flowing through it. Provided tempreture remains the same.❤
You are my favorite techer in Khan academy. You made physics more interesting for me

Plz Khan Academy bring him back, there are a lot of students these days, who needs ur valuable techings. And ur videos will definitely be the best. Thanks 👍
No words to tell how much this video help me ...really hit me hard
Ese padhai jati science,great work,thaks bhai...mujhe tarif Krna nhi aata iske liye sorry Krna.
Your voice and explanation is splendid, Sir
Dear sir,please upload all about electricity as transformer motor generator and theorem (basic electrical engineering lesson)😊
Sir you are one of the best teacher in in the world.
you are next level sir
I saw the video in English also but I got it way better in my mother tongue hindi
Very impressed pura dimag main rahgeya thanks ❤️❤️❤️❤️❤️
A very nice explanation sir .
physics is great .and you are our best physics teacher .
Very nice explanation sir
I think no one can explain it better than you
Thanku sir
U r damm good sir
Excellent teaching👍👍👍👍👍
Very nice amazing explaination 👍👍👍👍
Very nice 👌👌👌
Very
Very nice voice with explanation 👍
His voice is so interesting and curious❤
Sir,
Your teaching style is so nice.Can you upload the chapter Current Electricity of class 12?
nice videos sir we r understanding easily.
Sir plz upload all videos of science in hindi
This video is very helpful for me thank u sir
Sir i have a doubt that
As in metals electron are free.....means one or more e- leave their atom and just rome....so this means due to loss of e- atons of that metal should be an ion(most cases) always ???? True or not
Very nice 👍👍👍
Wah sir g wah zbrdest
Sir exam ka bht km time hai.....pls sir km time me important que....jyada btao
Kya hi to padhate ho bhai tum ❤❤❤
Thx sir 😊 For Good STUDY TIME WITH YOU👍
Sir you are 👏👏👏😊😊😊
Very nyc voice☺️
👏👏👏👏It's the best way to teach physics,thankyou so much sir, now this topic is so easy to understand for me........thankyou sir thankyou so much sir........☺️☺️☺️keep it up sir.......🖕🖕🖕🖕
❤️❤️❤️ thanku
really sir you are a best sir all of sirs
Very nice 👍👍👌👌 t
just and just outstanding
ngl khan academy is better than any online platform
excellent explanation
I have one doubt. when water flow below the naro place of the tank. Who it is dffected? I think it is full free at this place and gravitational force directed acts on it. Please do clear my doubt🤔🤔🤔
Thinner the area = the resistance That's Why
It will take more time for the water to flow in the narrow region as the decreased cross section area allows less water to flow at that point.
Well Explanation...
Please khan academy, bring this teacher back for class 12th science
Thank you sir so much 🙏🙇🙇🙇 sir plz biology class 10 ki vdo la do 🙏🙇🙇🙇🙏
Super 🙏🙏🙏
Thanks Sir for starting Electromagnetism series....
Sir but why we use that convention only and yahi thodehi ek wajah hai current to high potential se low potential hi jata hai waise unhone sahi bola tha.
Yeah but in case of electrons motion they were observed from negative to positive
@@pari_0152 yes bro beacuse of repulsion and redox reaction.
@🗿moai🗿 since electric field is from higher potential to lower and so electrons experiences force opposite to electric field that's why electrons move from lower potential to higher this causes flow of electrons!
@🗿moai🗿 actually total energy is conserved .
@🗿moai🗿 first of all potential energy +kinetic energy is conserved and when electrons flows it experiences resistance through kernels (fixed atoms) that's why they loose their kinetic energy and again they gain it!
Here there is no point of potential energy!
Thank you so much sir
Please sir upload full chapter of electricity
Thank you sir 😊
Yaarr mjaaa aagya kasam ss
Sir science ke poore chapters ki video upload kijiye please
Great Explanation ! 👏👏
Thank you soo Much @khanacademyIndia❤️
Kon kon is ko lockdown ma deh rha ha😂😂😂
Same bate kitne loge khedi sala dimag khrab ho gya is bat ko sun ke 🖕
Sala
Hmm you all seeing in lockdown but I am from future

Sir mujhe apka sakal dekhne ka bohot man karta hai
12th physics ke notes bhi daliye sir
Please send video of gravitation
Sir
Akkir current tho waise bhi flow hora tha us mai resistance kiyo lagate h ,any reason
Direct agar battery ke do terminal connect karo ge to short circuit ho jaye ga, kyun ki electric charges ko flow karne mai koi rukawat nhi ayegi aur iski wajah se heat boht zyada produce hoti hai.

Super
Sir per unit charge ka matlab kya hai
Per one coulomb of charge
Perfect understanding
Why we still follow that electricity move from positive terminal to negative terminal but in reality electrons move from negative terminal to the positive terminal?
We can't change all those previous works and theorems based on the movement of electricity from positive terminal to negative terminal
please tell me this lecture is for class 12th or 10
10th
10 th
Sir class 10 ki chemistry ki video kab tak aa jayagi please bataye
THANK YOU SIR
Why is resistance important?
To prevent overflow of charges
Maja aa Gaya
