MOSFET Transistor Basics & Working Principle | Electrical4U

MOSFET stands for Metal Oxide Semiconductor Field Effect Transistor. The mosfet is a capacitor operated transistor device. The capacitor plays an essential role for operating a MOSFET. We also call the device as Insulated Gate Field Effect Transistor (IGFET) or Metal Insulator Field Effect Transistor (MIFET). Why we call so we will understand when we look into the constructional features of this transistor device. We must take a look into the construction of MOSFET while going through the working principle of mosfet. Construction-wise we can categorise the device into four types.

P – Channel Enhancement MOSFET
N – Channel Enhancement MOSFET
P – Channel Depletion MOSFET
N – Channel Depletion MOSFET

I'm 73 years old and now trying to learn a little about
Electronics, NICE explanation, Thanks William Orange county, ca.

[michaelwolfe]

This is probably one of the clearest, most educational videos I've ever seen! I've been confused about this subject for hours but this cleared it up instantly

[phillipdonnelly]

The BEST explanation of a how a mosfet works by far. I watched few videos but this is the Clearest explanation. Thank you.

[mahimabrahma]

Got the concept in 7 minutes which I couldn't understand in class from 7 days

[abhaysahu]

One of the best videos on Mosfet. So simply explained, a stuff which is not easy to understand from textbook. Crisp and to the point. Thanks for the video.

[scomputers]

Really clear and simple explanation. Best one I’ve seen on YouTube thank you.

[fahadisrar]

Conceptually, very lucid and clear...Thanks!!!

[JamenAiyewaole]

This is the best explanation that I have seen on mosfet. Thank you

[saikadiyala]

really u made me to shud out tears from my eyes
i was finding for this kind of video but at last i found the diamond a lot
really i love this channel supper explanation much agian

[chao.l]

Your explanation just cleared all my doubts! Thank you so much!

[nikitadas]

This was such a terrific explanation. Thank you so much!!

[techmath]

Totally Understandable. Thank you Ma'am so much....

[mixiomi]

I must say thank you. It is the best demo to understand the n mosfet with clear graphics. Great but easy to understand that working of MOSFET. You have beaten all the high end glamorous video and monotonous and academic lecture by professors, in explaining the model clearly. Great work! Keep it up.

[shubhamkothari]

Beautiful. Loved it. Thank you so much!

[AshishGupta-lboh]

great and simplified explanation. it is worth watching

[unubiopaluwa]

Thank you for this explanation. And much thanks for the pace of the video, its perfect.

[sohamsdays]

This is one good video. Thank you :) !

[CaptainDangeax]

Thank you for this very clear video about mosfet

[Dushku]

Loved the simple, illustrated presentation.

[ramasamyjagannathan]

Clear and lucid style explanation, now I know the working principle of a MOSFET. Thank you very much.
