MOSFETs explained

In this video I am going to explain how a MOSFETs works, also a metal oxide semiconductor field effect transistor.

[fabianm.]

When you get to this level of explaining things, it means you have grasped the concept. Thank you very much Sir..

Wow, this synthesized 3 hours of lecture in the best way possible

[merlynesmith]

You are one the best trainer and teacher I realy llearned from you, keep helpin usplease.

I am a retired auto tech and building a daily driver with reliable robust parts and creating as service manual to go with it. My biggest hurdle in planning for the correct n-type Mosfet, is correct on voltage within saturation.
I am running a cooling fan across a radiator type device to cool the automatic transmissions fluid. Using a can/probe type NTC thermistor at 10k (Standard for 25 degrees C) but also to make it adjustable, I am placing a 10k pot as a voltage divider for gate control of an N-channel Mosfet. I believe with most data sheets that 2-4 volts for “On” voltage for the Mosfet, I will use a 100 ohms resistor. I will use an external relay oversized to ensure a robust circuit and ease of diagnostics, repair, testing and a large auto-type relay box, found behind the glove box of Park Avenues & LeSabers. It is narrow and takes little space, yet holds 12 relays and 14 fuses. I am very good with auto electronics, but ok will enough knowledge to build a circuit on a bread board...without setting a fire!
They sell digital readout type temp sensors for $10. But they loose their setting if disconnected from power. I don’t want that! I will spend $20 now, to save $150 later. Your thoughts on a mosfet? My eyes are bleeding after 77 data sheets and 94 videos that mostly play music. Great for music lovers, but I want to get one thing done per day, while waiting for my S1-L2 lumbar fusion. It’s not fun or easy, but not related to fixing cars since the late 60’s. Thank you for a clear explaintion and I have to admit, I was saying out loud to draw the vertical dotted line...and you did! God bless you.

This guy is a magician. Hours of lecture that went in one ear and out the other explained so simply in 12 minutes

At 5:32, you said.. When Vgs is high, Vds is high. I am a bit confused. When the mosfet conducts, the voltage across should drop. Please clarify

[ricardomardi]

You have mastered the art of translating electronics concepts. Thank you! Excellent video.

[abicelis]

Very well explained. One of the best videos out there explaining MOSFETs. Great job!

[youfrancis]

This is VERY HELPFUL.
Thank you especially for: not only verbalizing the effects on Current, Resistance, and Voltage; but writing also. That really makes a world of difference--it reinforces those points!
Seriously, you should teach. You have an intuition for clarity.

finely someone has taught me well.After 8 other videos and a whole lot of wasted time.I thank you sir.

[tanaysarkar]

Keep making videos brother
You solved my doubts in few minutes
Thanks man❤️

[vigisbigtm]

You are a very good teacher. thanks for the video.

[yuwumi]

Excellent video, very concise and time efficient

[jackreynolds]

Great stuff, thanks so much. The graphs were amazing, really helped.

Very cool and simple way to explain the MOFSET ! already watch many video about MOFSET but too complex for me to understand

[DannerPlace]

Very good video, thanks for posting it.

[kevinchall]

This video was explained perfectly! Thank you very much !

I'm new to MOSFETs, let me begin with that, but I'm not seeing something here. I'm stuck at 5:50.

If Id is close to zero, it follows that Rds is very high. Fine. However, this would imply that Vds is also high. If current is not flowing, then there's in implied high resistance. How then would Vds be low?

[Kartoffeljoghurt]

Great videos, really helps with my exam prep!

[ghazanfaransari]

Thank you. Well explained. Good video learned a lot.
