Seebeck & Peltier Effect - How Thermocouples & Peltier Cells work?

🔥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 ☺️

this is a carbon copy of an explanation video steve mould uploaded a month prior
Hope to get the same teachers all around the globe to make physics as interesting as it always was. Thanks a lot.
Excellently structured explanation of the seebeck and Peltier effect, best I've seen.
Bro your visuals are so incredibly helpful. Thanks for the explanation!

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.

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 💙
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.
One of the most understandable way of explaining. The jumping part is clear now
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!
This was awesome. Thank you so much for the amazing explination and visual aids showing how these fundamentally work.
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!!
You made a informative video mate. I enjoyed watching you demonstrate these devices. Thanks for the upload.

Much waited video from you, Big fan of 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.
So happy to watch this video. This is the best explanation one can ever give.
THANK YOU for this! I am always looking for science projects to work with to teach my Grandson. Now I can explain this better.
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.
thank you so much for cutting open the peltier cell. the video was amazing
The best explanation I ever saw for these effects!! Thanks
Very well explained, and good animation as well
Amazing explanation and a very didactic one! Thank you very much!!!
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.
Amazing animation for given a knowledge... Very nice keeping up...
Really cool explanation and animations !!
Insane videos which help us understand how stuff works
Congratulations Bro your video has been recommended for MSIN classes in FEUP portugal
Nice piece of work. Really help me doing my mechanic works 🥺

very beautiful explanation
Hi, I come from Indonesia, thank you for making videos like this, I got new knowledge, and the animation is fun, not boring
Great tutorial and explanation
Great video sir. It would be interesting if you make a similar video on piezoelectric disc
Brilliant video, thank you!
This is the best explanation. 😍
Very good explaination👍
noice.... cool info.. i am currently learning on transducers like thermocouples and lvdt.. this video was helpful
I have my final exam of air conditioning and refrigeration tomorrow and this video helped me alot, thank u man❤️
Very well demonstrated.
Informative. Useful. Calming. Inspiring. Life-changing. Enjoyable. Heart-warming. Other.
Very nice explanation
amazing explanation sir
Your didatic is amazing!
Great animation and explanations, thanks, man. Hope more people will discover your channel
Amazing explanation 👍
Thanks for sharing you explained it very well
Best explanation yet
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 !
Wonderful video! Thank you very much
i love how you say "so called peltier module" every time :)
Helpful video
Super Information Keep Good Work. Thanks Brother 👌👌
Good presentation
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!
Nice Animation
There are many interesting projects to do with these cells :D

Thanks you very nice video I learnt so much from you.
This is so good
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.
Awesome vedio many thanks..
keep spirit and keep posting, i love this video
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 😅
This makes more sense than coolent getting cooled to a 30 degrees with a fan when 100 degree out
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.

Great Video 😍💯
PLUTO introduced me to this concept
very cool!
Is it possible to create a type of circuit where the thermocouple generates a potential that drives a Peltier, and then the thermic differential of the Peltier provides the heat difference required by the thermocouple? I'd imagine that the size of the thermocouple would have to be very large in proportion to the Peltier, but what use could such a circuit have? I know perpetual motion is considered impossible, but could you have a closed loop that would only require a small external heat source to drive the internal loop? I wish I knew more about the physics of such things, but that's why I'm grateful to Electronoobs for creating such videos as this! I'd love to hear what potential uses and practicalities such a device might have!
Excellent 👍
The best explanation ever... Can you also make a video on Dshot, oneshot, multishot, proshot,etc. protocols? Pls...

really cool hot topic...and i like the way you speak english...thank you, nice way to explain how things work, and also you have a nice perspective in your mind... what is the meaning of your tattoos? what is the meaning of each one, and why did you get it? just for interrest, pardon if it is too personal...
God tier video.
Thanks!
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
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 ...
The two alloys used with Seebeck effect is similar to a hot water gravity circulating loop.
Here are some thoughts. So the less dense elements and the more dense conductive elements have a stark contrast in electron output. What if we went more extreme? For instance, Aluminum paired with something as simple as lead or bismuth? Even in a liquid state the lead/bismuth would have contact with Aluminum. Aluminum = 13 CU = 29. This grants us a 2.23 electron output before Ohms. Al has 13 electrons while Lead has and Atomic number of 82. A possible 6.31 electron output. Low melting point problem. Tungsten would also work in contact with AL. 74/13. You wouldn't have the melting point. 5.69 output You would likely have a galvanic corrosion problem. :/ The more massive metal steals electrons from the inferior metal and releases hydroxides causing corrosion. OH- Conclusion: The corrosion is likely the reason this power system is limited to small uses like Thermal Couplers. What are your thoughts?
Wow explanation.
Also used with temp to hold open power valves as to measuring , like air brakes ?
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.
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.
Subbed. Thanks for your clear and concise interpretation. Have you an interpretation of the |Lorentz Force?
Please provide the specifications for two different alloys wire
thanks sir
