How a MOSFET Works - with animation! | Intermediate Electronics

In this tutorial, using some animation, Josh explains how a MOSFET works. These Metal Oxide Semiconductor Field Effect Transistors are strangely straightforward in their operation but the logical leap to create them, and the way they have changed the way the world works is amazing. While there are different types of Field Effect Transistors (FETs), the MOSFET is a great example of how a field effect transistor works in general. He also briefly touches on how a Field Effect Transistor is physically made. Check out the transcript of this tutorial on the CircuitBread website - www.circuitbread.com/tutorial...

You're great presenter, thank You!

I lofe your voice in the first thirty seconds. I can listen and learn from you.

VGS VTH and VDS > VG-VTH
did I misunderstand anything …!
saturation

[@haianh9341]

@@sureshchattu5211 May be, he confuse between Vgd with Vgs. I think "gate threshold voltage" is replaced to "gate to drain voltage".

Hi,
I really ❤️ your video.
I am a teacher from Bangladesh. Most of student don't understand english. I like to teach them in your way.❤️
Please, can you tell me what software you use. Specially the 3d animation part.
Thanks. #respect.

[@kuki3693]

Great video. You have explained it better in 5 minutes than my professor have in 3 hours

[@rBennich]

"Kuk i" means "Cock inside" in Swedish. Have a nice day.

[@redstonecaptain8007]

True

[@muneeb-ahmed]

Nah your professor explained t better you just cleared your concepts and revised the topic here

[@srmanginsay5855]

Yah I agree with you.

[@adrian4961]

Came here after my first Electronics class and learned everything we talked about in 5 minutes. Thank you

You learnt about mosfets in your first electronics class? I'm learning about it in my 2nd year of university lol

Great info, graphics, and editing!

[@CircuitBread]

Thanks! This is one of my personal favorites, to be honest.

[@andrey-kramer]

@@CircuitBread hi
what program you use for 3D modelling MOSFET ? (from 0:56 and later)

[@efeyzee]

@@andrey-kramer Any 3D modelling/animation tool will achieve pretty much the same results. If you want to get into 3D modelling, you can get started with Blender since it's free and has a pretty wide community so you can get help if you're stuck

[@agniveshkurup5709]

Had a ruckus in finding good videos that makes you understand the working ....then found this channel...... life saver❤

[@maibster]

Single Best explanation of Mosfets I have ever seen on the internet, GOOD JOB!

[@angie25601]

Thank you! The explanation is very understandable with the animated image of the MOSFET structure

[@johnnybuoy9551]

BEST video HANDS DOWN.. I had no clue about MOSFETS, in fact I kinda got intimidated how TF these monsters worked. But it explained me in the best possible way.

[@rafaelmedina546]

After watching multiple videos on this subject this is the one that actually made it click. Very nicely done and thank you.

[@rodolfonetto118]

Excellent video! Specially because you taught the principles beforehand. Also, your observations about the terms and your explanation about "region" were great - you are an excellent teacher, sir!

[@CircuitBread]

Awesome, thank you!

[@jumpyalexa8526]

Thank you! This made things so much clearer, and got to the point.

[@ahmedhussein6163]

Thank you so much, the 4 videos about NMOS in this channel are beyond fantastic, amazing , unbelievable. Immense talent on how to explain , what amount of knowledge to be delivered in what video to avoid confusion, awareness of what parts are confusing for students and how to tackle them. short videos but the amount of work and preparation put into them is huge. real professional work. thank you thank you thank you.

[@rockirol1]

So well explained and yet so underrated!

[@s8computers781]

Thank you very much for this. Although I struggled with certain terms, the fact that you acknowledged it can be tricky at first; helped me to think I need to stick at it and it will eventually come. You have a good presentation style and I look forward to watching g more of your videos. Thank you and greetings from Sheffield in UK.

You sir are awesome, my professor has some old-school books/presentations. In them you get lost after the first 2 sentences, while this video explains everything in less than 5 minutes, thank you again and have a good day! :)

Really useful

[@THE_ONLY_GOD]

I am not a degreed electronics engineer, HOWEVER this is how that ACTUALLY seems to work: when circuit between pos (gate side) and neg termimal are connected the electrons flow to that capactitor gate and thus fill that channel and current starts flowing across that channel. Thanks in advance for saying THANKS!

We're hoping to create a repository of simple circuit examples on CircuitBread.com that would include various use cases for MOSFETs. I'm not sure how quickly we'll get it live or how fast it'll grow but we are expecting to start building that in a month or two.
