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.
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.
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!
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.
It's like explaining how to drive, starting from scheme of engine. Interesting, but useless knowledge. Dan started from practical part: just press accelerator and move! :) That's why this video HUNDREDS times more useful than "pretty presentations" how electrons pass PN edge.
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.
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.
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!!!👏👏🙌🙌🧐🔋⚡️⚡️😅
@@SimpleElectronics Do you have any videos on how rf circuits work? I want to make a transmitter and a receiver circuit so i can make a 3d printed rc car lol
@@grantscott1686 Don't bother. Just buy ready built TX and RX receiver modules. It is considerably easier and they can be pre-certified. You are not allowed to transmit on any frequency you like.
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.
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
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.
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 RUclips 30 years ago; I might have picked this up sooner!
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.
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.
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
No it is not that simple. You need to go look up transistor biasing, active and saturation regions, output characteristics curve, Ic versus Vce for differing levels of Ib.
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!
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.
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!
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.
It's a LOT simpler to just use a purpose chip like a TP4056 instead of just transistors but I could likely build a small circuit for basic charging with transistors
@@SimpleElectronics Thanks. Looking forward to it. There are quite a few videos on the subject, but none that include a circuit diagram and an explanation on how electricity interacts with the components used in the circuit. Most of the stuff simply has a music soundtrack without commentry. Leaves one absolutely mystified!😙
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.🙏🙏🙏
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 👍👍👍
The base resistor can be anywhere between 200 ohms and 10k ohms, depends on your transistor and your load. 1k is really easy to find so start there. For the LED - try 1k ohms as well and adjust it if you need more brightness!
@@SimpleElectronics Do you know if I can control a tri color led (red - green) with both pnp and npn transistors; because I would like to switch from red to green with a single led, but the circuit confuses me because the tri-color led has a common terminal, thank you very much for your kind response
@@rebandido777 You will need to see if it has a common ground or a common power, and once you know that, you can install the appropriate transistors on the non-common lead. The type of transistor will depend if it's a common power or a common ground - make sure you pay attention what side of the load each transistor type needs to be!
Hello... Nice explanation, easy to understand. Just one problem though. You still perpetuating the wrong concept that current flow from positive to negative, I'm pretty sure that you know is not true but you still teaching that concept on the basis of traditional use of an old concept. I believe we should adopt the correct concept's that humanity continually discover and shed the old ones in order to correct and advance in our constant pursued in understanding our world. There is no benefit in keeping old wrong concepts. I really like the showing of the real components on top of the circuit drawing, that helps grasping the concept easier.... Thanks you 😊
Since current flow is instantaneous, it really doesn't matter the direction of current flow. The "conventional" method is what's more easily ingrained in beginners' minds and once they get the core concepts, it's easy to swap to electron flow.
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.
Great video. I want to turn on /off a relay based on a resistance that becomes zero or 45 ohms. (The relay is very small and needs 12 volts to 16 volts to operate) How can I use a transistor with this varying resistor? I will try to make it but would like some expert's opinion and design. Thanks

What possible projects can anyone like me be thinking about if I am still stuck with that FUCKIN' Canadain dollar?😀
I finally found some lecture after searching for weeks which cleared the concept❤.hats off to u
