I would have probably gone mad with the vague definitions in the textbook as I HATE learning stuff I don't understand! Thank youuuu for your selfless video! Love u khan academy 😊😊😆
I have been confused with voltage and potential energy since the start of the semester, I had read books, watched a lot of videos and tried to pay attention in class but nothing had really helped until I watched this video. Thank you so much!
This is perfect. So many TH-camrs ranting on about irrelevant crap that just confuses you even more. This is so clear and I finally understand this idea of potential difference! Thank you.
Dude I still could not understand how potential difference is needed to have a continuous flow of current because it is about TRANSFER OF ENERGY AND how is that connected to a continuous file of current?
Finally understood what teachers, professors and books have been trying to explain me. This channel is hands down the best thing that has ever occurred to me on internet
As soon as I hear this guy voice I convinced my self to learn new thing. My Teacher is so boring a think he haven't good coarse about this concept and I told him to follow this guy. Thanks a lot mahesh your student from Ethiopia, East Africa.
I am not going to lie here, buy this teaching in way far better than any other vids that I have seen explaining this concept mainly because of that kids slide drawing.
Can u tell me if i connect only a wire to the bettery ..no bulb is involved ... then the electrons won't loss any energy..then what will happen?..electrons will continuously gain energy while passing through the bettery...?... confuse

I think the direction of the flow of electrons is wrong here cause electrons would always flow from negative terminal to positive terminal and current flows in the direction opposite to the flow of electrons. Any one correct me if I am wrong.
yes, it was mentioned in the video. for simplicity we are taught with the direction of protons as their direction is considered the direction of electricity. Once watch the video again.

@@jibankrishnamuhuri5518 I think if come to reality the charge will actually loose potential energy by moving as it convert into heat energy , so if they keep moving they will loose some potential energy and ultimately before reaching the battery of the negative side it will loose its potential energy and they regain . That's why when you connect a circuit without a load it loses some potential energy not all but some and it regain the energy through the battery
So if the voltage drops to zero after passing the resistor, then what's pushing the electrons to move toward the terminal of the battery? Can someone explain this, please?

@@jibankrishnamuhuri5518 No, I guess there will be no loss or gain of energy...it's because an empty glass can be filled when it becomes empty If here, the bulb is not connected the battery will get the electrons already having enough potential energy...so no loss or gain of energy I am not sure whether it's right or not but hope this only the logic behind it....
Again, What made the electron move from the positive pole to the negative pole ? is the poles themselves or the chemicals that push them or the difference between their potential energy ?
Hi! So first up the electrons DONT move from positive to negative pole but the other way round, that is from negative to positive. Also, the chemicals inside the battery are generating energy which act on the electrons to make them move across the circuit.
Sir,in the example with potential difference of 1.5 V, what if there was no bulb, then positive charges will still keep on flowing from positive side to negative(i.e:electrons will keep on moving from negative to positive side of battery).But there wouldn't be any resistance as per our assumption, so no heat will be generated.Then will it still do 1.5 J work/coloumb?
Using his analogy one could have been more succinct. If mgh represents gravitational potential energy (PE), Voltage is analogous to the "gh" bit or gravitational acceleration x height in the direction of acceleration. In electricity gravitational acceleration is represented by electric field E (which also is acceleration) and height by d (displacement) along the E direction. Just as multiplying gh by mass = mgh (gravitational potential energy) so multiplying Ed by q = qEd = electrical potential energy. The "Ed" bit is also called Voltage or EMF. Thats it in a paragraph Recapping, gh is analogous to Ed or Voltage or EMF or "POTENTIAL". Multiplying with q gives Potential Energy (PE)

Since energy can neither be created nor destroyed ,what about the kinetic energy of positive charge .Are we neglecting it against heat loss? Bcz we r considering complete potential energy supplied by battery going in heat loss in bulb then what about the movement of charge in wires and bulbs. Plz explain sir.
Is it something called as electric potential energy which supports the electrons to move through the battery and to lose it as heat energy ? Please can someone help me get it right Meaning, how do we get the potential energy in the first place ?
As soon as I hear Mahesh Shenoy's voice, I smile and know that I'm going to have some fun while I learn. Good job.
you can hear him smiling and laughing, being genuinely excited about what he is teaching
Sme I also feel
awesome
The same😊
Same... I love his channel flothead physics

Agreed
Your teaching is God's gift for me and also other students. 🙏🙏
No doubts left.....
literally understood so well I could cry
Yah, I WASTED 1 WEEK ON THIS!
Mah physics teacher so bad I could cry. Khan Academy saves the day.

Thank you sir and I 2ould like to have such understanding vedios
Amazing
Great video. Sir! I really love the way you explain.
Just keep making great videos.
Excellent explanation. I wish I had heard you before , so I could have taught my students in this way. Now I will use this method. 🙏

best video on volt
Thanks for this video
So if the voltage drops to zero after passing the resistor, then what's pushing the electrons to move toward the terminal of the battery? Can someone explain this, please?
I see It cannot never be zero as it just lost what it gained but still have its main potential
You are the best thanks
can u plzz explain tge electrochemical process inside the cell? which prvide the energy to the +ve charge
as long as u guys are here there is hope alive in us.... genuinely speaking
Finally i get it💖😭
Thank you SO MUCH!
Woow
Even ad a physics teacher
I just happen to be learning potential difference all over ....what are they teaching in text books for heaven's sake

OH thank you for making this understandable without another hose analogy!
And why is always explained with the ONE thing you do not want to mix with electricity?
works even for collage students!!
I have been saved by an Indian guy on youtube thank you
Tysm dear
Thankyousomuch sir!
Now I understand

GOOD EXPLANATION SIR/;/;/;/
Hello, what about the kinetic energy of the charges moving? Isn't there energy lost through the wire?
Thank you!
Exactly my question.

thank you soo much
