🔥Another theory video. See my explination of how the thermoelectric effect works. See the physics behind this process and how a thermocouple and Peltier Cell works and what we have inside.
Important: I've made some serious mistakes and badly expressed myself in some cases. 1. When we heat materials, metal is a good conduction of heat as I tell in the video. 2. Conduction occurs when a substance is heated, particles will gain more energy, and vibrate more. Particles, not electrons as I show in the heated glass pots example. Second, these molecules then bump into nearby particles and transfer their energy to them, those energized electrons. 3. In the potential animation, electrons should flow from V- to V+. What I actually showed in the video was the current path. 4. So, as I tell in the video, when we heat the metal, the PARTICLES vibrate more and the free electrons will simulate getting more separated on the hot side and more pushed together on the cold side. That creates a small voltage difference. Sorry for any other errors if there are. I'll try to update my errors the best I can. Have a nice day ☺️

Conduction occurs when a substance is heated, particles will gain more energy, and vibrate more. Particles, NOT electrons as I show in the heated glass pots example. Molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases, that's what I meant on the "voltage difference" creation animation. 3.

No dude everything was perfect nice video
# well done #keep going
Also, the statement that in absolute zero particles are not moving is wrong. At absolute zero, particles have the *lowest* energy possible.
You are a true scientist because you admit & correct the mistake you made. Mistakes are no problem (I do it all the time - oh, my..) as long as you correct them ASAP - preferably before "magic smoke" starts to ooze outta your (expensive) electronic equipment.. Aww - bad..!
And yep, I have a very nice day - because of your wonderful explanation and very nice video.
Hope you have a nice time too and thank you !

I have a question. If you have a circuit running using the seeback effect, you are pushing electrons from one metal to the other. It sounds like you will eventually end up with a low concentration of electrons in one metal, and a high concentration of electrons in the other - sort of like how a battery discharges. Is this true? If not, how? And if it is, does that mean that thermoelectric generators using the seeback effect can only go for so long, or can the electrons flow back from high concentration to low like a rechargeable battery?
Thankyou 💙
Literally the best explenation of seeback effect! Thx
Thank you :)
Electronoobs is a very underrated channel. He definitely deserves more views
this is a carbon copy of an explanation video steve mould uploaded a month prior
Excellently structured explanation of the seebeck and Peltier effect, best I've seen.
Hope to get the same teachers all around the globe to make physics as interesting as it always was.
Thanks a lot.
You're a great teacher. Thank you. I'm building a passive solar walipini and I was wondering how I turn heat from a wood stove into electricity. This was my first step in that journey.
Bro your visuals are so incredibly helpful. Thanks for the explanation!
I had no idea these were related, or how either of them worked. Now I do and you've made it entertaining to understand. Thank you!
One of the most understandable way of explaining.
The jumping part is clear now
Truely satisfying!! I have been looking for the explaination of Peltier effect but nonebfound could provide this satisfaction! Now I got why the two materals are requied for the thermoelectri cooler. Thanks! Keep up with this wonderful works!!
Much waited video from you,
Big fan of you
This was awesome. Thank you so much for the amazing explination and visual aids showing how these fundamentally work.
You made a informative video mate. I enjoyed watching you demonstrate these devices. Thanks for the upload.
Really thank you :=)
really nice visual explanation of the electron energy difference and the thermoelectric effect connected to it
Finally, a proper explanation for thermoelectric effects!! Great video. Thank you for the information.
THANK YOU for this! I am always looking for science projects to work with to teach my Grandson. Now I can explain this better.
thank you so much for cutting open the peltier cell. the video was amazing
So happy to watch this video. This is the best explanation one can ever give.
Great stuff, better than physics class at a university. i could have watched this for an hour, i'm interested in buying or making a very large one with hot water panels on one side, and well water on the other.
Very well explained, and good animation as well
The best explanation I ever saw for these effects!! Thanks
Really cool explanation and animations !!
I have my final exam of air conditioning and refrigeration tomorrow and this video helped me alot, thank u man❤️
Bro your channel is recommended by UA-cam I have seen on various devices congratulations 👍👍👍👍👍#fan from india
Nice. Thanks for the info :)))
Just for other viewer's sake, for his self-disabuse point 3, what he showed in the animation is NOT the current path, but electron path. Electrons flowing from V- to V+ is correct only at the outside part of the battery/voltage source, but within the battery, electrons flow from V+ to V-, and the seebeck wires as he showed is the battery itself, which uses thermal energy to drive the electrons to OVERCOME the electrical field internally and flow, which is why it's called a source.
Also for his point 2, I guess it's more correct to use the energy increase and more vibration of Electrons that leads to electron density disparity, other than the Atoms as a whole, to explain the voltage formation, because the atom density difference on two ends won't form a voltage because atom as a whole is neutral, so I think it just is the electron itself that got more energy and drift to the cold end that forms the voltage over the two ends.
Having commented this much, I have to say his video is awesome, and I learned the key knowledge from it and highly appreciate it.
Amazing animation for given a knowledge...
Very nice keeping up...
Amazing explanation and a very didactic one! Thank you very much!!!
Congratulations Bro your video has been recommended for MSIN classes in FEUP portugal
I understood about this seeback affect and peltier effect 👍👍👍👍
Thank you for such a wonderful explanation
Love from India 🙏
Nice piece of work.
Really help me doing my mechanic works 🥺
Clearly understood!!
Best explanation
Great visual presentation. Don't worry if it wasn't perfect scientifically, you grasped the main meaning and the way to make it "visible"---in fact, able to be visualised. Yes, if we enter deep into theory electrons are not even dots but waves etc., the model would fit the theory perfectly in rarefied gases where the electrons would be the atoms--the ions, in fact!, and they won't collide with each other, but this is fine as it is. I did subscribe. Keep up the fine work !
This is the best explanation. 😍
Nice explanation.. Great work
Hi, I come from Indonesia, thank you for making videos like this, I got new knowledge, and the animation is fun, not boring
Thank you for answering my question! Thank you for sharing.
Great tutorial and explanation
Great video sir. It would be interesting if you make a similar video on piezoelectric disc
Insane videos which help us understand how stuff works
I am grateful to have found this gonna share with my friends
thankyou so much! for the very first time knowing about peltier my mind has blown. You explained it so clearly. 👏👍
very beautiful explanation
Informative. Useful. Calming. Inspiring. Life-changing. Enjoyable. Heart-warming. Other.
What a brilliant explanation. I'm your fan. Thank you so much.
Amazing explanation 👍
Very good explaination👍
Very well demonstrated.
noice.... cool info.. i am currently learning on transducers like thermocouples and lvdt.. this video was helpful
Your didatic is amazing!
🤯 Ordered a Coolify neck air conditioner and came here to see how the peltier module works. Good video!
Very nice explanation
Brilliant video, thank you!
Helpful video
amazing explanation sir
I ordered some Peltier modules a few months ago but haven't done anything with them. I just ordered some "one wire digital thermometers" this morning, and look forward to playing with temperature control.
I think that an incubator with temperature and humidity control might be fun, throwing maybe an ultrasonic mister into the mix along with some BME280 sensors.
That sounds interesting. Maybe you share with us your project :) keep up
Super Information
Keep Good Work. Thanks Brother 👌👌
Best explanation yet
i love how you say "so called peltier module" every time :)
There are many interesting projects to do with these cells :D
And theory as always well explained!
Good presentation
Nice Animation
Thanks for sharing you explained it very well
pretty good explanation mate. I have read your mistakes below and current flow still confuses me as I was educated on one standard which changed a couple of years into my trade.
As I said, good explanation. Terry from Australia.
Wonderful video! Thank you very much
keep spirit and keep posting, i love this video
Acabo de descubrir tus canales y son una joya. Acabas de ganar un suscriptor en ambas. ¿En qué programa haces tus animaciones? Son muy didácticas. Éxito.
Still u say that the inner level is low energy and the higher levels are high energy. Isnt that the other way around cause the electrons on the higher levels require less energy to free?
Great video thank you!
This is so good
Nice one
Wonderful...keep ot up...
Now that’s a great video
Very nice!
I come from the Seebeck family on my dads side, pretty cool to see the Seebeck effect explained even though it kinda went over my head 😅
Why did I just find you? Instant sub.
Thanks you very nice video I learnt so much from you.
Great Video 😍💯
Great animation and explanations, thanks, man. Hope more people will discover your channel
Wow best explanation ever thank you
:))) Thanks!
Awesome vedio many thanks..
Красава, все ясно и понятно рассказал👍
Thank you!
The best explanation ever... Can you also make a video on Dshot, oneshot, multishot, proshot,etc. protocols? Pls...
I'll have those on my "to do" list...
God tier video.
very cool!
Excellent 👍
Helpful
This makes more sense than coolent getting cooled to a 30 degrees with a fan when 100 degree out
Please provide the specifications for two different alloys wire
What an explanation
can both hot and cold be utilized at the same time say there's a section of a device i want hot but another section to be cooled so the heat dose not reach that section
I used a aluminum plate to adhere a grid of peltier plates in series... and replaced the side of a beer cooler with the plate. Add ice in the summer or hot water in the winter to the cooler and I get a little power. It was just for fun.
A friend of mine has one TEG stove fan, unfortunately it stopped working and my friend is looking for an answer to why it stopped working? Any idea guys? Could it be that the eletrons in the TE materials have run out? Or what else? Thanks.
is there a ratio for how many watts we can produce per degree?
Wow amazing
thanks sir
The two alloys used with Seebeck effect is similar to a hot water gravity circulating loop.
Also used with temp to hold open power valves as to measuring , like air brakes ?
Thanks!
could someone please write the minute where the procedure of the work starts(i need it specifically to write a laboratory work project)
Nice video. now i'm wondering what's the efficiency rating at, and could it be an alternative or a derivative to solar panels, or maybe t-n-reactors ,i've never liked the turbines ...
Wich alloy will bear the most cold temperature bro ? The one made by high mass element or the light one ? For ex. Copper and iron where copper is the high one and and iron is the light one.. who will be the most cold ?
