Thank you for the last minute explaining why one would use a transistor as opposed to just pushing a button. That's when it really connected in my head.

So THAT'S how those little suckers work! I understood that they were basically a switch that was triggered electrically. I knew they were really fast. And that's the full extent of my knowledge of transistors. I knew they were NPN or PNP, no clue what that meant. In 9½ minutes, you have allowed me to grasp, what turns out to be a relatively simple concept. And you taught me how to use it. These are things that have alluded me for a long time. Thank you for your clear and concise explanation and demonstration. You bet I subscribed!

Thank you for this series. For years I worked in a radio repair shop, all we ever repaired was valve radios and record players. So as a result thats what I'm used to working with and never understood transistors. The books I read were far too confusing. You give nice and easy explanations with practical demos.

Great explanation. I'm a Certified Electronics Technician, and when I got certified many years ago, transistors were always the hardest things for me to understand. Seeing this video made them much easier to understand. So thank you.

Thank you for using a visual explanation, this helped me a lot!!

Very clearly explained. I thought I understood the basics of transistor operation, but your SIMPLE description of how each could be used (NPN VS PNP) lit the lightbulb. Also the use of resistor in the base circuit makes perfect sense now. Thanks. You've just earned a new subscriber.

Now is this so difficult for a university teacher to do that as an intro to transistors? Thank you for the video.

Wow! Thank you! Until watching that I had never understood transistors properly.

Thanks for this video helped alot. Your approach is great, not bogging me down with all the confusing details , just what I need to know !

Oh wow! After searching for days trying to find simple explanations like this that I can understand, here you are!! Absolutely brilliant. I've subscribed immediately and now I'm off to watch anything else you've uploaded! Nice people you Canadians!

Awesome job dude, thanks for the timestamps. Also great explanation on using transistors with a micro controller. I haven't heard a great concise explanation before, and the visual really helped out!

Nicely done. I'm looking forward to more of this.

Thank you for making it as simple as possible. I loved it.

Thank you very much. This helps me understand a lot more. Nicely done!

Thanks man! Im nearly 40 just getting into this stuff. Your explination made total sense for me. Thanks again, mate :)

Awesome explanation. You answered my question I had in mind at the end of this video.

This was an excellent beginner video! Getting back into electronics after 20+ years and this was an excellent visual. One thing which I learned (or didn't realize until now) was the reasoning for putting the load on the emitter or collector side.

Thank you so much...the thing about where the load should be saved my life!

Great video. I'm looking forward to more of this kind of thing.

Good and easy explanation and demonstration, Thank you man

Thank you so much. You make learning basic electronics so accessible to people like me who have been wanting to learn but don't know how and where to start. Hope you will inspire others to share their electronic expertise.

"What the hell is the point if I have to click the switches anyway" I was always looking for that question, thank you very much for this video 🙏

MY GOD I wish more electrical how-to videos would add the devices into their drawings!! Awesome sir!!!

Something that has been bothering me for a long time is knowing the transistor. You are very blessed, you explain very well.

I've watched a few beginner/basic videos about transistors, and while many are good at explaining the underlying physics, all of them make far too many assumptions about the other components that they may be used with. This is the first (and best) I have seen because while it is far from exhaustive in scope, it shows the two basic types in two common configurations, with clear useful guidance about which side to place the load. Basic rule-of-thumb stuff that gets you moving, then gets out of the way. Bravo. I have subscribed.

Hi Thanks for the series! This was a bit to basic for me, but I am sure you'll move it on and keep explaining it as clearly :)

Excellent presentation, I need more so I have subscribed and thanks so much.

thank you so much for teaching us this clearly.it was very easy to learn because of you.You just earned a new SUBSCRIBER🥰 Hope you make more videos like this. You're awesome!😎 Thanks again.

This video helps me a lot! Thank you!

Good video. Cleared up a few things for me.

Sub earned. I love the use of live components in combination with the diagram.

Thanks, love the explanation , master.

Excellent video - very clear

That is by far the best explanation of transistor operation I have ever heard and I have been in electronics all my life

I worked on electronics for years, but we followed a step by step building directions. I now am self learning how the components work and your way of teaching is my way of learning, I like it. I almost just the gun and asked what the he**, why don't I just use a switch...and then you rapped it up for me. Thanks for a very good video ! I'll be watching more.

My man, this video is awesome! I actually paused the video, drew the schematic on paper, and then tried it out myself after watching the video!! I just got a bread board recently and would love some beginner projects to start working on circuitry. Please make more just like this! Super informative, and I love the visual aids. Excellent work!!!👏👏🙌🙌🧐🔋⚡️⚡️😅

Great tutorial, thanks!

The best explanation of basic transistors

You are a brilliant teacher! Thank you :)

I finally understand how transistors work and it's thanks to this amazing channel. Thank you!

FANTASTIC VIDEO

Very nice introductory video I would like to see more 😁

Good job. Until this video, I didn't understand why the base of a PNP needed low voltage to conduct, the opposite of an NPN. Thanks.

Very practical. Very good.

Very nicely explained and most informative video

Thanks for making that understandable for somebody farting around with electronics a little later in life!

Yes I understand now

very educative. Thank you Regards

This video is awesome, I subscribed

very well explained.

Great job 👍 Thanks

great tutorial.. can u make another like this but for ic ?

Great work! 👍😃

Very nice video ! Very explanatory and helpful. Keep it up !

Just watched your video, excellent

I Subscribed it .. Because of this video.....very easy to understand. ..

Thanks for sharing I think I can use your PNP and NPN phrases to help me remember. Once you attach a phrase to it your more likely to remember it 10 years from now even if you have gotten away from the subject a bit.

Great video

Dan, your video is the FIRST video about all those pnp/npn, which practically explain what to do with 'em. Thank you for simple lesson! Am I right that all diff between PNP and NPN is simply... *polarity* of a control signal? Make scheme with LED on the left or right of transistor is not a big deal.

Clear explanation

Good job !

dude after all these years , 8:17 was explained me a lot about transisitors. And i think this is the best video how transistors works Thanks and keep up the good work

What an excellent video, production, audio, and information. You are terrific in the explanation and how you present this material. I like your description(s) using the simple drawing, then switching to the real electrical components. I am a fighter jet mech (30 yrs), needing to brush up on my electrical knowledge. Electricity is not my strong point in my background/expertise. Thank you for all that you do for us! I wish we had UKposts 30 years ago; I might have picked this up sooner!

Finally I got it! Transistors have kicked my ass for several days. Thanks for the very informative video.

Thank You so much

Bro this is best video.

Was struggling with remembering which one is which but your little trick helped, thank you.

Thanks . Problem solved 🎉

Great explanation and thanks for the visual representation. I think this could have used some more practical examples, because LEDs can also be powered by microcontrollers so it's still kinda hard understading what you could actually use a transistor for, or how to pick them, what to look for, things like that.

Hi great video, can you also show the whole circuit like how you connect the gnd and where you connected it

Are the resistors of the same value? I refer to the resistors on the main and control circuit.

Was helpful...

Nice video, keep it up, thanks for sharing it:)

Thanks ✌️

get well everbody 🥰🥰🥰 Thanks forn sharing🥰🥰🥰Thanks forn sharing🥰🥰🥰

Finally, some enlightenment on transistors. Thanks for a lucid, logical explanation. Could you do a similar presentation on how a transistor works in battery charging, with the red and green LEDs in action? I'm not an electronics guy, just seriously interested.

thank you

Thanks!

This explanation was the piece that was missing from my understanding. I was always putting the load on the negative end of the transistor and wondering why it didn't work like my intuition said it should. Thank you!

Thanks 👍

Good one. Hwow about North. Points North and Never points North ? Compasses can be visualised that way. Thanks.

Hello , Thanks a lot for your Teaching, Explanations and Efforts. They are very illuminating for me. As a beginner i would like to ask, just depending on the Led light. Does transistor serve as a Switch between two Loads, switching them on and off? Does the Base work like a Contactor, Relayer , for one or more Components on the Circuit ? God bless you and your kind of People.🙏🙏🙏

Nice one

Good one

haha love the points in perpetually and never points in memory tool!

Tq v much

very well explained transistors as a switch, to make it even more simple a transistor works as a switch when a small current is applied to its base it then connects its other two legs together or you can say it shorts the collector and emitter in order for the current to pass through it like a switch, and the type of current applied to the base vary according the type of transistor NPN or PNP. If the type of transistor is PNP, Negative side of the voltage should be applied to the base of transistor and if the transistor type is NPN, then positive side of the voltage should be applied to the base of transistor. Today is my first day to learn about transistors and this was the second video i watched on youtube for learning about transistors. correct me if i explained something wrong about transistors, i want to learn about them perfectly. Thanks in advance

Thanks

Hats off

at 5:08 ,sir , are we using a common base configuration?......can we make the same functionality with common emitter/common collector?

good video

Hi😁 brilliant video, I've never done any electronics and I'm trying to learn 🥴, I'm making a wire buzer for my children and I want a green light for on but when the buzer and red lights are on the green light will go off 🤔 many thanks brilliant 👍👍👍

I would love to see an oscillating circuit like at the end but sans microcontroller. Built just with transistors. And there are a LOT of people looking for the same thing. Maybe usi g a tank circuit or just clever connections between transistors.

you're underrated bro

Hello, thank you very much for your videos! I have a question what are the values ​​of the resistors? I would like to practice at home thank you

Pnp and npn can both work as a switch or an amplifier. Npn are better as switches, pnp are better as amps.

Just what was needed for a noob like me.

Really good example,but I’m am now wondering how two concepts apply. Eric O, often talks about “high side and low side switching” is your first example a representation of high side and second one low side switching? And are the terms “sourcing” and “syncing “ applicable here? Thanks

The only thing I didn't understand is how the current from the 9 volt 🔋 flow. is it fo emitter to base ?

BC 548 general purpose npn transistor. What number is Pnp transistor ?
