🔥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 ☺️

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.
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!

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 💙
Much waited video from you,
Big fan of you
I have my final exam of air conditioning and refrigeration tomorrow and this video helped me alot, thank u man❤️
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!!
This was awesome. Thank you so much for the amazing explination and visual aids showing how these fundamentally work.
really nice visual explanation of the electron energy difference and the thermoelectric effect connected to it
This was amazing and very clear explanation thanks 😊
I have a question, I have once heard that peltiers are the least efficient way to make difference in temperature could you explain why ?
noice.... cool info.. i am currently learning on transducers like thermocouples and lvdt.. this video was helpful
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.
There are many interesting projects to do with these cells :D
And theory as always well explained!
Very nice explanation
Great video sir. It would be interesting if you make a similar video on piezoelectric disc
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.
voltage drop doesn't especially mean that it really is getting lower it just describes the voltage across an impedance of any kind
Why did I just find you? Instant sub.
Helpful video
Very good explaination👍
Really cool explanation and animations !!
amazing explanation sir
Nice one
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?
could someone please write the minute where the procedure of the work starts(i need it specifically to write a laboratory work project)
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
@6'40" should replace "electrons" word by CHARGE. Current is not due to "electrons" "moving", but charges (quanta of the electric field energy). The electrons are the media the charges "move" through. They're carriers of energy as much as antenas are carriers for radio (electromagnetic) waves (and antennas don't go walking from one city to another to "carry" the electromag energy to there....)
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
So first current flow from hot to cold ,then positive to negative?
Amazing explanation 👍
Wonderful video! Thank you very much
If we can get voltage by using only 1 mateiral, than why we are using two metals is seeback effect?
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.
Hlw sir your video is great someone is copying your clips I don't know if you are aware of this a RUclips 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
Also used with temp to hold open power valves as to measuring , like air brakes ?
Please what is the name of the software(logiciel) you used for simulation
This makes more sense than coolent getting cooled to a 30 degrees with a fan when 100 degree out
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 ?
Hi, can you post a video on how the salt water engine works?
Best explanation and very helpful for my studies!!!
Please Provide the specific of each part
aaaaah, so now I understand what Harrison Ford did in the Mosquito Coast!
Why don't you create another channel to teach coding and programming languages like python. It will be very helpful for beginners in computer programming like me 😀
I wish I would have time for another new channel...
@@ELECTRONOOBS do you have another job?? Please tell something about your qualifications and career ❤
What an explanation
Great Video 😍💯
Very nice!
So steam pipes next to nitrogen pipes can create energy. Who you like to help me make a pipe assembly for general mills?
Missed to be one of early birds.....anyways, nice explanation.... :-D
Second alloy becomes cool because, thermally oscillating election from first alloy has quantised oscillations, because of quantized energy levels.In case of alloy 2 there are also quantized energy levels,which need not be be of same energy as that of first alloy.
As we know , electron can occupy an orbit in second alloy only if orbit is corresponding to same energy of electron or of less energy.The probability of getting same energy orbital is very low.And thus electon has to loose its energy in order to fit in lower orbit.This loss is energy can be in form of radiations.so alloy 2 itsel will become cool by radiating
Bro I'm planning for a project in thermoelectric generator using solar power... Need your contact for any assistance required... Pls help...
3:30 Whose temperature is being measured????????
That flame temperature???
Wow explanation.
Excellent 👍
Animations 100/100
top class
hmmmm is that why it's like 6 times less efficient than the vapor compression method
Now I am going to do some Showup in my class😂.
Hail Electronoobs !
Electrons are really naughty!
Why stop there why not use 3 types of metal in a loop
how is the controller supposed to-WHY STOP THEREEEEEE
We have extreme temperature freely available on our planet but we couldn't make single voltage to benefit societies why.. We can't think beyond money making.
All atoms has electrical charge,😮
I'm feeling bad while typing this but this video became boring very early.
Efforts in animation and scripting are visible, but please try to make something that we may not find somewhere else and is worth watching.
Thank you for the feedback! I usually do videos on topics that I like :=)
牛逼
Fake hair
not ideal for US English speakers
This explanation has got a lot of problems
fake fake
Hope to get the same teachers all around the globe to make physics as interesting as it always was.
Thanks a lot.
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.
video beings at 2:20
You made a informative video mate. I enjoyed watching you demonstrate these devices. Thanks for the upload.
Really thank you :=)
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.
One of the most understandable way of explaining.
The jumping part is clear now
Bro your channel is recommended by RUclips I have seen on various devices congratulations 👍👍👍👍👍#fan from india
Nice. Thanks for the info :)))
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 !
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!
PLUTO introduced me to this concept
Why peltier can be broken if we don't put fan on the hot side?
Hi
Brother please, can you make it more simple to understand.🙂
Wonderful...keep ot up...
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
Im the 100th viewer
Please provide the specifications for two different alloys wire
Who is here to understand this effect after watching Pluto Pluto 😂
Watching the last episode right now and googled it immediately haha
Amazing show 😭

@@hyde_stopStealingMyUsernameyoure not the only one😂
Informative. Useful. Calming. Inspiring. Life-changing. Enjoyable. Heart-warming. Other.
God tier video.
This is the best explanation. 😍
No. It makes no sense. All physical explanations are wrong. Thermal energy vibrates molecules and atoms, not electrons. Electrons flow from negative terminal to positive terminal, not the way you presented on the graphic. Search on wikipedia at least first...
Sorry for my bad explinations
@@ELECTRONOOBS If you keep this video, people are going to learn wrong things. I think it's reasonable to correct it, or make an "errata" one with the correct explanation.
Super Information
Keep Good Work. Thanks Brother 👌👌
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.
thank you so much for cutting open the peltier cell. the video was amazing
Amazing explanation and a very didactic one! Thank you very much!!!
Pretty good video thanks!
is there a ratio for how many watts we can produce per degree?
First
Ive been trying to figure out how to pull electricity from heat for years, so its just a wore around a cooling fin, that also contacts the hot part, which moves electromagnetic particles through the wire. So the negative would be where the cool part comes off, and the positive would be where the hot part comes off. Or opposite. Not sure. Extremely simple wow
nice info.. Where are the thermoelectric/thermocouple panels about the size of home solar-panels? Big money talks. I guess this stuff get's the back set? 😎 Thanks.
Coolness, this'll be used to augment solar, tidal, geothermal, fusion, hydro & wind.
So the Seeback & Peltier Effect are one and the same?. Will the thermocouple be reversed, will it's welded tip produce cold or heat like Peltier if you put a different or the same voltage on each wire, say put one live wire into alloy 1 and one live wire into alloy 2 wire?
God bless.
