University level lesson/teaching that I'll never forget. Yet down to earth, well explained and examples given, in less than 13 minutes. REALLY good video. Thank you Sorin!!

I like the direct explanation, I remember sitting in a class many years ago listening to a lecturer droning on 1.5 hours on this subject, we all left wondering what he was trying to say. my boss explained it like this direct as Sorin has, perfect

I don't understand how the gate opened when you touched it with tweezers? What was the gate detecting when you did that?

utopiaopera the gate was detecting an intruder. 😀 Just kidding. Even I'm curious. 👍

Ray of Creation I believe the gate was sensing a slight resistance either thru your body or a direct touch with the tweezers.

My knowledge increased about mosfet. Thank u sir.

I never tought about learning electronics with Travolta!! Awesome channel!

I'm a little late to getting to this video but very valuable knowledge with these mosfets. Thank you so much once again Sorin!

Great explanation! finally a Mosfet understanding made really easy.

Thank you for sharing your knowledge with us !!

Youre doing a great job, I learned a lot from you. Thanks!

Tnx for your time and your videos!

Very good demonstration

Bravo Sorin. Mulțumesc frumos.

Thanks for the effort teaching these things......great job!... :)

Great to understand mosfet working thanks.

Great sharing mate! Thanks!

Fantastic explanation and demo ❤

Fantastic explanation and demo 👏

That's very helpful thanks sir!

That was really helpful. You are doing a great job as usual. Thsnks.

thank you Sorin! your a good teacher!

This was a great and quick explanation, you had the parts already connected and working so you just proceeded with the details, thank you very much Sorin

nice video sorin! thx

Thx Sorin.

good explanation. thank you.

best teacher. si we need more vedios from you to repair laptops perfectly with out schematic diagrams. help us

Thank you that was clear and very useful.

that makes perfect sense, Now i understand mosfat

Great explanation! Thanks

I love this guy. You know, he's like your favourite teacher back at school. Well, he is for me anyway. Keep up the great work. You should start selling merch such as T-shirts, baseball caps and such. I would willingly buy anything with your name on. Would identify me with the other likewise nerds, no offence! Until then, Patreon here I come!.. >

Thank you for explaining

Nice work!

Keep up the good work

THANK'S SORIN YOU'RE GREAT

Thanks for explaining Mosfet.

thankyou for your tutorial .

Thank You sir respect the first time wat i understand the testing mosfets

Very well explained

great sir

Thanks

sorin you are doctor of doctors

this guy is very great....gets stuck right in there so even i can understand

Awesome..

TיThank you very much

Simple but effective. Very useful video. What will happen if we switch the plus and the minus. The circuit will close again but will the led blink.

if you switch, will be short because of the diode

last silly question. If we switch the polarity and use PNP instead of NPN. The diode is in opposite direction.

Great video once again. I have a request, if you have time: Could you fix a laptop but using schematics so we can understand how we can read schematics? Or at least explain us an schematic of a random laptop, and how things are related to themselves.

Not all PCB designs are the same my friend :) and understanding schematics is also important.

hello my fellow hero!

Sorin loves Friday & Coca Cola 😁

First mosfet is a invertion voltage protection, the second is an adapter presence detector

there is two mosfets shown?

Good day Sorin could you tell me what brand name and model of the multimeter you using please. hope to get a reply as i plan to buy one that will do my work better.

cheers mate got bargain tonite xbox 1s 50 quid thanks to its fixed your star love videos

Is it acceptable to have "a short" signal through the secondary Mosfet's beside "the coil", even when the gate is drained or grounded to close the gate? Are some Mosfet's designed to sound as a short between the two sides of a Mosfet that is not the gate?

good sir

Hi Sorin or should I say Master Sorin? Thank for posting all these videos. I am one of your subscribers and really enjoy the content of your videos. It may seem a bit of a silly question, but in your opinion, is it worth learning how to repair computers and laptops? A friend of mine thinks it’s not worth it nowadays, because there are a lot of people doing it, including young teenagers and people want it done for next to nothing. I love learning new skills of all kinds. I am at the moment learning how to repair car ECUs and thought that if could also learn to repair other electronic devices, such as computers and maybe mobile phones, it could be useful and profitable. I live in the UK. What is your opinion on this? Many thanks. Kind regards, Joe.

Ha, ha, ... if you are living in uk, yeah, learn. You know how is with what you said 'because there are a lot of people doing it, including young teenagers and people want it done for next to nothing.' ? Well, is the same as with the phones repair.... 99.9% of the shops are repairing phones but only replacing parts like screen, battery etc. Same with the laptops. The shop owner are looking for to hire someone doing repairs based on electronics knowledge from over 7 years and he could't find anyone. I'm the only one doing this. So, it is worth learning? I will say yes

Thank you for your reply. I originally trained as a car mechanic, but left the trade in the middle nineties. I came back to the trade a few years ago and have been relearning all the new skills that go with diagnosing the electronic faults by proper methods, not just replacing parts to see if it works. I love all sorts of knowledge and love learning new things every day. You’re right, they’re a lot of people out there replacing parts and they actually believe they’re techs. I’m going to make sure I learn all I can about electronics, not only because it will be useful, but also because I love it. Thank you for your advice and please continue posting your great informative videos. Thank you very much. Kind regards, Joe.

@@electronicsrepairschool I believe they go for more paid jobs, no? You could land an EE job somewhere too. Knowledge is almost always valuable but not necessarily for the job we think. Hard to find a doctor to do the job of a nurse at a nurse's salary. That's the trick.

Please teach how to use analog multimeter to test any faulty component in a motherboard

I don't understand how the gate opened when you touched it with tweezers? What was the gate detecting when you did that?

So it's just a switch. Thank you!

ive bought a dell xps 17 inch worth 300 for 40 quid. it has a short when charger ia plugged in. ive stripped it down and immediately next to thr power rail from the dc socket there are 2 mosfets. one mosfet gas readings on each side. the other just reads 1 on every pin. does this mean it is the cause of the short?

That's a potatosfet 😃 thanks for the explanation

Is n mosfet bad if i get 8.5v on source and 14.5v on gate? first mosfet near laptop batteryconn(battery is 8.7v ,charger 12v) when on charger(batt unplugged) gate and source are same(8.5v). Thanks!

hi, you had a video when you draw a power supply , where it is?

get DCA75 - Atlas DCA Pro Advanced Semiconductor Analyser, no need to guess if something is dead or not! But price is ridiculously high.

Maravilha! Muito bom! Obrigado.

using mosfets allows the battery to have more life because it uses current instead of extra voltage like transistors that use/ high volts ?

PI EXPLAIN THE LCD SCALAR OR T-CON BOARD IN A SIMPLE WAY THANK YOU

Why do you check the short showing Volts rather than Ohms?

hi isee you long time sir

OK sir, but in Laptop theory 19v to drain pin and we expect 19v output on the source pin, to get 19v output on the source pin we need to open the gate , for the N channel mosfet needs more voltage on the Gate than the input voltage to open the channel to source , so how the the touch opening the channel?.. on a laptop it's not possible to open the gate by giving lesser voltage on the gate .. I am confused

Sensitive,
