How FETs Work - The Learning Circuit 

Hands down the best explanation of MOSFETS and JFETS on RU-vid! Thanks! 👍🏻

I had this all in college but with these Visuals I see it so much clearer. I wish I had access to these visuals back then.

This channel always help me for my studies. Thank you so much. During lockdown my college is closed but thanks a lot to channels like of your one and RU-vid for availing a online study platform for us students.

This is the best explanation of FETs I've come across youtube. Well done!

Karen, your videos are awesome !!! . really appreciate for the great knowledge. Very simple, descriptive and clear understanding.

The visualizations in this series really help!

Thank you very much, this video was so helpful to me, and I'm looking forward to seeing many more.

This was really clear and concise! Very easy to understand!

Thank you!! This is the best explanation I could ever hope for! I though I could do it on my own, but I was mistake.

I can't believe how good this video explains the topic. Unbelievable

This is really good stuff thanks for putting this out there!

Excellent presentation. This has been helpful. Thanks

Great explanation. So clear. Well done. I now understand something that I have never understood.

Thank you for these videos!

Best explanation I've had. Thank you

The best explanation video one could find is this

It gives more clarity and understanding. Thanks

Fantastic explanation, thank you very much.

Thank you so much . Keep the great work going

Excellent presentation 👍

Best transistor video on the internet that I've ever watched

So well done. Thank you.

Your explanation is good and clear 👍

Thank you so much for your help

Very nice thanks for your help and training

Great simulation. Thanks a lot

Thanks, Karen!

At 0:40 I think you compared a PNP BJT with a N-type MOSFET, because the drain should be the equivalent of the colector, gate-base and source-emitter.

thank you very much, loved it.

thanks for the class .............god bless you

Thank you so much, Karen!

We will get good knowledge in how to work transistors ❤

Your videos are owesome thank you

..good visual explanation, thanks👌

Cheers Karen!

Man if I had a teacher like this during the transistor classes a school I might have actually paid attention.

This explanation was SPOT On.

great video

Nice Informative video

Could a FET be used similar to a potentiometer (varisistor)? Even if a lot of heat would be created to waste energy

Thanks for the generosity to teach !! I would suggest to slow down the pace of the teachings, to help beginners get a better grasp of what's being said. Thanks again.

Great video Karen. When will you do one on OP-Amps?

you make me cry ..you are great teacher ^_^

2:21 why the Gate Source voltage needs to be lower than the Drain Source voltage to a depletion zone happens? In a normally PN junction the higher the voltage is, the higher is the depletion zone (if it is reverse connect)

wow ! thanks !

very helpful

Mam, Ur are very very good at teaching,u are just mind blowing,amazing mam,thank you for your information ❤❤❤

Thanks sister

Thank you Thank you

Can you explain for us how to calculate the gin's of transistor?

When you come back to teach, I will come to listen. I like to see women teaching.

06:22 : How is it possible that the drain current can be larger or smaller than the source current in a Mosfet? (Apart from the tiny charge to initially charge the gate.) Is this not an error in the video?

❤ thank you

Tks Beauty girl, exelent video, 💯

Seems that the D-mosfet was not forward biased to increase the channel width in the last portion of the video, wouldn't the gate need a positive charge,drawing negative charges into the channel from the substrate, increasing the width of the channel and there by increasing current through the mosfet, the battery, it seems, should of been switched in polarity from the last screenshot but wasn't? Great videos though and much appreciated, thanks :)

Very good video I like

So enhancement mode MOSFETs work more like BJTs?

great!

thank you clever girl

aren't the VGS + and - reversed(+ should be on the top) when mosfet is operated in enhancement mode? at 6:04 . Greetings and thanks

Simply put it, in a n channel jfet, you increase the negative reverse bias gate voltage. - vgs . In a p channel jfet, you increase the positives reverse bias gate voltage, + vgs.

how to find SMD capacitaor value

FETs are the solid state of Vacuum tubes so what about a FET version of the CANADIAN WESTINGHOUSE 656?, Drain:=Plate Source:=Cathode. Gate:=Grid

Hi Karen, I love your videos! Im just a bit lost in the word "bias", I don't understand what it is and in the video you say things like "the more bias the gate becomes" and "to increase the bias". I understand the principle of reversed bias or forward bias, I just don't follow it when it is used in a different context. Can you please enlighten me :) thanks so much!

Is p for + OR -, in all transistor

It so usefull

I understand it's function,what is about working principle of IGBT

Aww you're so sweet teacher love it 😀

You're awesomee

Love you

Simply put it, the difference is, vgs reverse bias voltage, decreases current flow, and the higher vds, in increases the current flow.

check out CircuitBread's video "How a MOSFET Works - with animation! | Intermediate Electronics" and "What are the Different Regions of Operation for a FET? | Intermediate Electronics" they are good complements to this video that fill in some little details that can clarify things

VGS battery terminal symbol (VGS) is not correct for the depletion MOSFET for the forward bias. Overall video is good, thank you!

There is a mistake on the video. You state the source on the FET is equivalent to the collector on the BJT. The opposite is true. Drain = Collector; Source = Emitter.

Cool... time to buy a handful of JFETs... I know that I'll pop a few by accident.

Hey could you try this software? scan circuit solver on the playstore!

Sound level is low compare to previous Video "how trns work".

I don't get it. Back to trying to fit a circle block into a square hole

Now Im less confused😎

Sister please slow down I'm confused. you explained great but I'm a dul student

You get my thumber... kept going on

my lovly carins

love you zelda shirt

Some practical examples of what they can do would be helpful.

Failed an interview at dream company because I didn't know what's JFET.

Something you may not know is JFETs behave a lot like vacuum tubes.

You give a lot of information very quickly. D channel this and gate that and n channel forward or reverse! We no sooner get a chance to look at the picture and you are on to the next one. I know, pause and look at it. Explanations and examples would help alot. I have been trying to understand these for years. Those teaching this know the information, are usually bored by the process, and can't see why we don't understand something that they learned years ago. The point is some of us are trying to learn what you have already learned and as yet cannot find a way to understand the subject. Slow down Sheldon or we will never understand Dark Matter (The Big Bang Theory)!

It is much easier to learn when your being taught by a cute teacher. All my professors were old men.

She an work in an auction as the best fast talker.

best video on fets on youtube, the others are too theoterical , lack content, amateurs or nothing didactic. ⭐⭐⭐⭐⭐

Aw shucks, I was hoping to learn more about my cat.

i felt like i was again 8 years old and my mom was teaching her stupid son how to multiply 3 digit numbers with 2 digits like a boss

I find it very disconcerting that you use + to - current flow

Too fast, slow down. Please

"There are two basic types of FETs." Wrong. You forgot about the most important (and most awesome) type of FET. The BOBA FET. ;-)

please go slowly..u had that hussain bolt shoes

...my professor took 4 hours to explain this AND IT STILL DIDNT MAKE SENSE!

I didn’t understand any of this

she just likes to talk fast

Veritas engr student gather here 😂
