How do transistors works? Beginner lesson 

It's not about if there are many videos on that subject.. it's how you deliver that knowledge to us, how you teach it and you sir are the best..

We were taught an easy way to remember NPN or PNP. An NPN has the arrow "NOT POINTING IN", NPiN. The PNP has arrow "POINTING IN", PNp . Hope this helps some remember.

It's just so amazing to see you bright like a Christmas tree (40,16) When your little experiment works ... a real kid, nice to know I'm not the only child My dad always said "The only difference between men and boys is the price of their toys" And now when I myself is getting old, then I have to agree with him ;-) Many thanks for showing and please keep up the good work ... ;-)

Hi, I'm now 63 years, I've recently started to learn microelectronica. I have a very long time ago sometimes done with electronics. But the search for what there is defective on a motherboard, I do not understand it so well. So I follow your beginning lessons closely. Keep up the good work. Thank you.

Nothing is ever boring with you Sorin, excellent teacher, even though I have a pretty good understanding of electronics i am still enjoying your beginners series, it will be invaluable to anyone starting out in electronics and computer repair, you are very generous with your free time and its something you have to be complimented on.

Hello my friend, I would like to thank you all very heartily for your videos you have made, my English is not good and I translated this slices with the google translater, sorry for that. I've been interested in electronics for a long time and have already read a lot about circuits and hardware, but as much as you explain it and show it is fantastic so that even I understand it with my bad English. I am always fascinated how to repair equipment and find the fault, without schematics and at each device, there are not many such people as you. Today's electronics students learn many things that you can not and can only exchange modules without looking for the error, I think that's bad and many people simply throw away their electrical appliances and buy new although a professional like you would fix the mistake in a short time for little money and thus also a significant contribution to environmental protection l I thank you from the bottom of my heart, you're a great electronics engineer and a very good person, keep it up.rnGreetings from Germany.Wolfgang

No, your lecture is not boring, everyone who wants to be professional should watch your videos, rarely anybody else across the youtube follows your approach. My best respect.

These videos are not boring and knowledged people can simply skip the vid. Its not about how many videos there are on youtube saying the same thing, its about different way of explaining it. I can hear the same thing from 99 people and not get it but hear it from that 1 person and it be clear. Keep making your videos and please make more beginning vids like how these components work in circut.

even 3 years later, you still the best teacher !

No your not boring! You are very good teacher. 👍🏼 please don’t stop I’m just starting to learn 👍🏼👍🏼

i'm a beginner , i'm folowing your videos since one year ago , this beginner lessons are just in time, thank you sorin i'm understanding what you say even if i'm a beginner, but not boring nooooo like how you say :D thank you sorin and good luck.

Hats down from Bulgaria my friend. Not boring at all. I have 13 years experience as field maintenance engineer for mobile netwotks and still it's a pleasure! Great job! Thank you! :)

I knew you were about one in a hundred as far as teaching goes. Now I see you are ambidextrous and that is truly one in a hundred - or less! Nice job my friend. I enjoy all your videos very much!

@Electronics repair school: Sorin - first of all you are definitely not boring. Something is boring when you don't get the idea, you explain the things pretty simply and it's not difficult to follow your ideas and the theory you are explaining. I would advice you to not over criticising yourself, because you are simply the best.

Hello, I'm Italian I started to follow your videos about a month ago .. well .. well .. I have never written on other channels ... your deserves! .. I also studied electronic but your explanations correct simplicity and calm make me remember many things forgotten .... thanks and sorry for the errors ... I have translated

Thank you very much, you are a very good teacher. You are the teacher I wish I had at school and the professor I wish I had at University. You made me realize that most people don't know how to teach in our education systems.

Definitely NOT BORING! I can listen to you teach all day!

Am following your lessons from Kenya,thank you for starting the beginner's class, once we understand the basics we are to be the best in our field of electronics. I salute you.

You are like one of those highschool science teachers that explain simple and easy to understand

I know most of the theory but I find these beginner videos very useful. The comments you make along the way show how you use the ideas for troubleshooting.

Thank you for taking the time to do all this for us. Fascinating.

for someone who wants to learn and become capable tomorrow to fix something nothing is boring.Without knowing simple things u cant know complex thing.So every detail is imprtant and nothing is boring.Thanks for the opportunity u give to us

Thank you Sorin.As a complete beginner that was a brillant lesson. I have learnt so much in just the first couple of lessons. It is nice you remember your childhood.Keep up the videos.

Sorin, I've been watching many beginner lesson videos to learn how to work with electronics. While those videos are informative, none are as entertaining and hands-on as your videos. I love that you're able to keep it easy to understand and demonstrate implementation at the same time. I do not usually comment on videos, but I wanted to thank you for taking the time to make these videos. I am finding them very helpful and you make it fun. I'm very happy I found your lessons. "So lets see some things!"

First of all I want to thank you for the videos , they are really helping me out to learn a lot . I like you style of explaining things . I must say that I don’t agree that the first two videos from this series were boring , even if there are lots of other sources where I could learn about individual components I am enjoying your style of explaining and I regret you did not go ahead with videos about individual components in detail with practical examples. Keep up the the good work !

I think Sorin's wife is as wise as Sorin. Lol. He really made this video very fun because he showed us how a photo transistor works in real life. He really is a great man by helping us learn his trade. Very few men would be as generous as him.

This is what I (am a beginner) really want. U r a clear basics.

It's nice to hear and see the information together; you explain it, build it, and draw it out. Thank you

Love the videos, I watch a lot of electronic videos on RU-vid. I’ve learnt more watching you videos than any I’ve watch so far. You’re the best.

I have been following all your video and by doing so I have already fix 2 dead dell Laptop and 1 acer laptop i admit i went to college in electronics but the way the teacher teaches us is more on theory and the way he explain it gets more complicated on my mind unlike what you are doing it makes more and more clearer thanks sir sorin ...

im really happy to find good people on line, Thank you sorin.

you are the best teacher ever. thanks for helping us.

I'm glad I found your channel. I have learned a lot, and I have enjoyed watching your repair videos. You have a great teaching disposition, thank you for taking time to do this.

This lectures of yours is absolutely informative.

Change a transistor in photo resistor was great. I didn't known about that. Thank you.

Hello Sorin ... Another very good video fom the "Master" ..... I am very happy today ... I managed to repair the first laptop that came in my hand. A Dell laptop that did not come on and the charger continue keep entering in protection mode. The problem found very quickly with the multimeter on continuity mode ... and finally tested with a power source at the charging port and my power supply indicates that it is short... I found a capacitor in short ... which also shorted the first 2 MOSFETs. I've been able to replace it and the laptop starts again :D... Thanks to you I found this problem very easy and fast ... These many hours when I watched almost all of your videos on this channel helped me find the problem very quickly and solve it. Thanks again ... and keep making the best videos for helping beginners like me and other people. I say honestly that it helps...

I like the way you are using discrete components to show their functionality. If someone is really interested in the lesson, it is definitely not boring. And don't mind about the language, it is perfectly understandable. I'm from RO and I have no issues getting the meaning of the lesson

Best channel in youtube history and the best electronic teacher on the internet !Multa sanatate si numai bine Dl Sorin !!! Va multumesc pt clipurile postate !

Brilliant for the kids to learn not only electronics but also maths. I substituted the photo LED to a piezo speaker for vibration sensation Amazing

This is so interesting! a trial and error live on the Video makes us really simulate many different scenarios and that is the best way to learn in my opinion. Thank you really so much Master Sorin!

Thank you, back to basic, great! Not boring at all, fun to watch! 👍

My Best Teacher in this World... I love you keep it up..We a learning on daily basis

Looking forward to your next episode on Power Supplies Sorin, should be worth waiting for.

That's very good video to understand how transistors works and what they actually can do. Thank you, Sorin. You're doing great job on this channel, really. Greetings from Poland! :)

Sorin, the mad scientist 😁👍, omg all I do is sit and watch his videos. I sure hope he doesn't let trolls discourage him to stop making these videos. People are learning so much from this man. All you have to do is sit and watch giving him a chance to explain the best way he can. He will make you raise an eyebrow. I just love it. If RU-vid would let me. I would like every video 100 times. Just because he is 100% trying to share his knowledge with people. Yes,yes I will call him Senpai. *Sorin is my Senpai.*

love you man, you are teaching from your heart

your videos are good and clear not boring at all you answer everything question and you clearly tell us whats going on and your video set up is good everything is great mic isnt 100% but its clear enough to hear what your saying and dose the job doesnt really need to be louder just cleaner sound but we dont need that

I love yo work and good kind heart. Wish I was in your country. I swear I would come and sit by your work desk to achieve such knowledge. You are ma hero.

I have great respect for the knowledge shared with us..everytime when you solve issues we also learn at same time its like real class room learn....its never boring...i spend hours watching ur videos...thanks you sir.. Regards from Fiji Islands

Another interesting video fr u....it is a video of school days fr those who used to play with electronic components & make small small projects but ..... very important when we start repairing of gadgets or trying to understand electronics ...anyway u hv given ur best efforts to make us understand or remember those days......thanks a lot.

I found the precious gem!thats your channel

People might find it boring but it’s slow witch in my case helps as I find it hard to take things in some times, the way u explain things helps me personally to understand it better, keep up the good work 👍

Keep going sir! Excellent educative video!!! We are looking forward to other videos explaining the functionality of other electronic parts!! Thanks a lot!

Thanks a lot for making such easy to understand electronic components understanding video.You are better person to be teach from. Thanks and kaap it up.Great and appriciated.

Wow, i will try everything at home today. Your lectures are wonderfull. Thank you sir.

First subscripton to youtube to follow your lessons. Like the way you explain simple ways.

Thank you, Master Sorin. I hope you teach us about capacitors, what they do in a circuit and how can we replace them if we don't have an exact match?

Brilliant class Sorin enjoyed it very much look foreword to next lesson, thank you.

Thank you for the teaching and the happy mode. great way to transmit your passion! If the electronic theory was on the emittor and our minds in the collector, you're definitely a base with > 0.6V :D

This is so good. You get to know things you won´t find anywhere else :-)

thanks for the lesson sorin

a very good lesson and the time is flying with u thnks sir

i love it. Nice videos. tanks from norway

Finally Saturday,,, can we get something this weekend sir?... Always eager to learn new things from your advanced lectures...
