How To Use Transistors In YOUR Projects! || Transistors Explained || Transistors As A Switch

[@ambiorixg12]

The clearest practical and theoretical explanation I found.

[@SimpleElectronics]

I appreciate the kind words!

[@bob2161]

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!

[@Bren39]

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.

[@frankowalker4662]

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.

[@xFalconFixer]

Frank, too many technical books do a poor job of explaining the basics. Many times, the simplest explanation is the best.

[@PaulGrodkowski-k3r]

What possible projects can anyone like me be thinking about if I am still stuck with that FUCKIN' Canadain dollar?😀

[@sky16678]

I finally found some lecture after searching for weeks which cleared the concept❤.hats off to u

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.

[@SimpleElectronics]

I appreciate comments like this, thanks!

[@yambo59]

I know this guys explanation is very good and very simple, and I understand it works as a switch, but much like math im ashamed to say Ive never been able to get an good understanding of electronics though ive tried repeatedly because its all very fascinating - but I must lack the brain cells to grasp it in a useful way, id love to be able to trouble shoot and fix vintage receivers but after years of reading books and now watching videos I have come to the realization that though I used to be an excellent car mechanic, when electronics came into the mix i was permanently lost in the shuffle - but im 65 now and no point in getting bent out of shape about it nowl

[@bobpurcell5662]

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.

[@SimpleElectronics]

Glad it helped

[@BrennanYoung]

Exactly the same with me. First time I've seen that base resistor explained in a way that made sense

[@timoshenko7846]

I have watched scores of videos trying to understand. Thank you. This is the best. It's like you were reading my mind.

[@petersmith5199]

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!

[@SimpleElectronics]

Thank you for the kind words!

[@KennyLeistman]

Thank you! Finally, a very simple explanation. I was actually able to create the same circuit and it worked.

[@TheSenseiKai]

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

[@BrennanYoung]

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.

[@daitedve1984]

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.

[@moepow8160]

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.

[@locifer696]

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 way of teaching well done

[@larrybud]

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.

[@daitedve1984]

That's the point! All diff is polarity of control signal.

As a kid I got interested in electronics seeing my uncle use a springboard kit, but every time I asked how a transistor worked he gave me some non-sence different answer that left me confused all my life about them (my uncle is a major jerk), I'm almost 58 now, and disabled due to a stroke, and your video finally explained it to me in a way that makes sense.. Thank you.

[@daitedve1984]

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.

FANTASTIC VIDEO

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

[@dennisjohnson8753]

Excellent video - very clear

[@ahmadkhalidhotak9399]

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

[@deang5622]

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.

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

[@salvatoreguiliano2429]

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.🙏🙏🙏

[@richardsandwell2285]

When thinking about polarity of Base inputs, it helps to take the middle letter has a reminder, for example PNP, the middle letter is N-for negative to switch on. And the NPN has the letter P- for positive to turn on. And for those who were thinking whats the point, wet your fingers slightly and touch the base lead and the battery, the transistor will turn on with the tiny current passing through your body, also try connecting a Photocell inline with the base resistor, these experiments will convince you.

[@rebandido777]

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

[@SimpleElectronics]

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

[@SimpleElectronics]

@@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.

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

[@SimpleElectronics]

Eric O from South Main Auto? Sourcing means providing a voltage and Sinking means providing a ground. So in my examples, the NPN is Sinking current (switching the LOW SIDE of the circuit) and the PNP is Sourcing current (switching the HIGH SIDE of the circuit).
