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

$2/5pcs 2Layer & $2/5pcs 4Layer PCBs: jlcpcb.com
🔥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. 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.

No dude everything was perfect nice video # well done #keep going

[@oniruddhoalam2039]

Also, the statement that in absolute zero particles are not moving is wrong. At absolute zero, particles have the *lowest* energy possible.

[@RavenTimish-hackertimish]

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 ! ❤😊😊❤

[@tjkim1999]

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?

[@illillc2284]

Thankyou 💙

[@Scilunar]

Hope to get the same teachers all around the globe to make physics as interesting as it always was. Thanks a lot.

[@adamsojka3345]

Literally the best explenation of seeback effect! Thx

[@ELECTRONOOBS]

Thank you :)

[@kaumohlamonyane272]

Electronoobs is a very underrated channel. He definitely deserves more views

[@majorfallacy5926]

this is a carbon copy of an explanation video steve mould uploaded a month prior

[@danieldewindt3919]

One of the most understandable way of explaining. The jumping part is clear now

[@SkibidiWaPaPaPaPa]

Excellently structured explanation of the seebeck and Peltier effect, best I've seen.

[@richfahrne9195]

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.

[@Zeiwon]

Bro your visuals are so incredibly helpful. Thanks for the explanation!

[@stuffnthings4106]

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!

[@ProCelestialEmpire]

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.

[@briankelly1240]

PLUTO introduced me to this concept

[@kennedy67951]

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

[@umihikari5199]

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!!

[@Mubashar345]

I have my final exam of air conditioning and refrigeration tomorrow and this video helped me alot, thank u man❤️

Finally, a proper explanation for thermoelectric effects!! Great video. Thank you for the information.

[@BasudevMahato-ev4qn]

So happy to watch this video. This is the best explanation one can ever give.

[@rizalgaming6787]

Hi, I come from Indonesia, thank you for making videos like this, I got new knowledge, and the animation is fun, not boring

[@BadazzRule]

🤯 Ordered a Coolify neck air conditioner and came here to see how the peltier module works. Good video!

[@nightcore.heaven]

really nice visual explanation of the electron energy difference and the thermoelectric effect connected to it

[@timucinbahsi445]

i love how you say "so called peltier module" every time :)

[@nhbyl]

Thanks!

[@austinjohnson4890]

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.

[@dhirendrapsingh6758]

Informative. Useful. Calming. Inspiring. Life-changing. Enjoyable. Heart-warming. Other.

[@Mavrick2787]

This was awesome. Thank you so much for the amazing explination and visual aids showing how these fundamentally work.

[@vannambienc3]

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 😅

[@utkarshgupta6134]

I understood about this seeback affect and peltier effect 👍👍👍👍 Thank you for such a wonderful explanation Love from India 🙏

[@mihailpetrovici5044]

This is the best video on this subject

[@48_subhambanerjee22]

noice.... cool info.. i am currently learning on transducers like thermocouples and lvdt.. this video was helpful

[@sudarshangurung8943]

I am grateful to have found this gonna share with my friends

[@LucasSoares-oh4bb]

Congratulations Bro your video has been recommended for MSIN classes in FEUP portugal

[@PapasAnimals]

THANK YOU for this! I am always looking for science projects to work with to teach my Grandson. Now I can explain this better.

[@sararajpoot8329]

Super Information Keep Good Work. Thanks Brother 👌👌

[@wanderlewis8552]

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 !

[@sadiqdp55]

this was a beautiful explanations, thankyou sir!

[@PablumMcDump]

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.

[@ELECTRONOOBS]

That sounds interesting. Maybe you share with us your project :) keep up

[@denisstrechie9139]

Why didn't you provide more info about the wires used at 3:40? I really want to know what material is used in those. "Como" and "Alumo" is not enough.

[@nicolaelintov2383]

Very well explained, and good animation as well

[@bmnihaal]

very beautiful explanation

[@haphamdev]

What a brilliant explanation. I'm your fan. Thank you so much.

[@arman6576]

Nice piece of work. Really help me doing my mechanic works 🥺

[@ViaAvione]

Thank you for answering my question! Thank you for sharing.

[@deddyrazar8478]

thankyou so much! for the very first time knowing about peltier my mind has blown. You explained it so clearly. 👏👍

[@SoumyaYaligar-jr4qi]

Very good explaination👍

[@suvetar]

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!

[@sameerUNO10100]

Insane videos which help us understand how stuff works

[@aerockh2725]

Why did I just find you? Instant sub.

[@lasersbee]

2:42... That is actually a voltage increase. 12:10... Those are not a bunch of different alloy metals. They are "P" and "N" (P/N) type semiconductor junctions in the peltier cell.

[@saitama4219]

voltage drop doesn't especially mean that it really is getting lower it just describes the voltage across an impedance of any kind

[@AmitabhAnkur]

This is the best explanation. 😍

[@jaomc7944]

Your didatic is amazing!

[@lucascesargomessquillante1192]

Amazing explanation and a very didactic one! Thank you very much!!!

[@ardutronic]

There are many interesting projects to do with these cells :D

[@ardutronic]

And theory as always well explained!

[@lukemurray5202]

Brilliant video, thank you!

[@Jalex92]

Electrons bouncing around is not temperature, if atoms bound together bounce around slowly/gently something is cold. If atoms bounce around violently something is hot. If the atoms bounce so violently the bonds can’t hold the substance together, it is called vaporization/evaporation. If atoms lose energy and the bonds between atoms is stronger than the energy an individual atoms has the substance solidifies/freezes/condenses. It’s called Kinetic Molecular theory and it’s very important. Bouncing electrons against atoms can cause molecules to also bounce (like bouncing a small rubber ball against a larger one), resulting in the substance getting hot, but they movement of electrons is not actually heat

[@devalsinhsindha8626]

amazing explanation sir

[@yeetyeet7070]

thank you so much for cutting open the peltier cell. the video was amazing

[@terryheimerl8674]

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.

[@ameristanbouli5063]

Wow best explanation ever thank you

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.

[@kombi8864]

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?

[@nicoiriart8577]

Really cool explanation and animations !!

[@selvamohanselvamohan3542]

Please provide the specifications for two different alloys wire

[@wesameed824]

Great tutorial and explanation

Amazing animation for given a knowledge... Very nice keeping up...

[@princepoudel7253]

Now I am going to do some Showup in my class😂.

[@KAFKUBA]

Pretty good video thanks!

[@North7able]

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?

[@markgreco1962]

Now that’s a great video

This makes more sense than coolent getting cooled to a 30 degrees with a fan when 100 degree out

[@qt1qg]

Hello! Do you know how thermocouple is impacted by currnet passing through it? How does mosfet leakage current would affect readings of t12 cartridge thermocouple? Some transistors have leakage current that changes from several microamps to several hundred microamps depending on voltage and temperature.

[@MrAnonymousme10]

Damn! Your illustration are easy to get! Even for a noob like me

[@liujunyan8244]

Great animation and explanations, thanks, man. Hope more people will discover your channel

Running current through wires causing one end to get very hot and the other to get very cold is something that if proved might impress me!!!

[@PriyankaKumari-ne9om]

Hlw sir your video is great someone is copying your clips I don't know if you are aware of this a KZbin channel named concept 1 by biomentors online they have used the same clips I didn't find any of your channel mentions there it was released 6 months ago
