How Transistors Work - A Quick and Basic Explanation

Do you know how transistors work? What is it about transistors that make them the building block of so many electronic items, like computer, laptops, smartphones and tablets these days?
What is a transistor? The transistor is arguably the greatest invention of the last century, or perhaps, one of the greatest of all time. If it wasn't for transistors, we couldn't have developed smaller, faster and cheaper computers, telephones, GPS devices, radios, gaming consoles, smart televisions, routers and a device -- no larger than a human hand -- that integrates all these marvels under the same screen.
This is a short, layman explanation of what is a transistor and how it works.

[@codmlover6008]

Thanku. I couldn't understand it still but I know you tried your best.

[@tiamen1255]

Lol

[@larslover6559]

Instead of being overwhelmed and discouraged by the 99% you didnt understand celebrate the 1% u DID understand... and guess what.. You will likely get motivated to learn more as you realise you are actually progressing a little...

[@larslover6559]

@Thomas thats great! yes im.learning electricity too these days. I try visualise every concept and try to really understand it. Think of knowledge little like eating. It must be chewed and digested. Knowledge then becomes undestanding.. Good luck and hope you get alot of wonderful discoveries!

great explaintion right everybody

Can I get an application for this?

Which app/ software u use to edit videos?

[@Scienceabc]

This one is made using Adobe Animate.

[@Pipolag1]

I'm an engineer and only after watching this do I now understand how a transistor actually works lol phenomenal explanation

[@alienrenders]

Flashlights? I don't think so. Maybe LED flashlights.

[@itskittyme]

There is really something wrong with education when I understand more from a 5-minute video, than the same information packed in a course of a few weeks....

[@andrewwebb4635]

Maybe you weren’t concentrating?!

[@Brainstorm69]

Great explanation building on semiconductors. I've heard this before but always forget it again, haha.

[@pangea6090]

I normally hate the "water"/"eletricity" metaphor (for explaining things like voltage), but in this case I find it very helpful. Next question: "How the HELL did anybody ever figure this out over seventy years ago?"

[@wasneeplus]

Why? I find it pretty helpful in general. Sure, the analogy completely breaks down as soon as you're talking about AC voltage or components in series, but as a basic introduction I think it's a pretty good one.

[@tristunalekzander5608]

That was the best explanation I've seen so far. A lot of people don't even describe it as a switch, which it is. It is an ingenious way of switching something on and off with no moving parts, no more, no less.

[@perrygogas]

That was excellent!!!

[@deimos_xe8639]

Can you not use 'positive electrons' as electrons can't be positive and if you actually tell the audience how electrons work and flow in circuits this would be barely dipping your toes into high school physics and saying positive charges can flow is ridiculously absurd did you even finish elementary school? Is this video a joke?

[@Cookieofdoom]

Looked for soundtrack to the game Transistor, and fell over this. I really didn't know what a Transistor was but now I do! Thanks!

[@R41Ryan]

I'm still a little iffy on how the physics in the transistor work, but now I got a pretty good idea about the design. This video is informative but short and concise. Good video.

[@Scienceabc]

Thanks. Glad you found it useful.

[@lakshmansagar9624]

The best and clean explanation of transistors so far. It would be good if you do another video on microprocessors too

[@rolandhafner2695]

I finally understand transistors thank god! Edit: Or thank you lol

[@maxwarfield6699]

Max Warfield Complete noob here. This is a good example of what, I'm not quite sure I understand, see, often you'll see an NPN BJT with that little arrow pointing away from the emitter, right? But the direction of the arrow of the collector isn't shown [tho we know, it is pointing away from the collector - NPN = Never Pointing iN]. So, my question is: HOW does current travel in the opposite direction of the "imaginary" arrow of the collector, when the current at the base, allows it? It's my understanding that current can only travel one way, in a diode, an NOT the other. And, a BJT is basically 2 diodes back to back, right? So, please explain this to me, I want to learn. Great video - make more. Cheers!

[@koppulapremsagar]

Another level...!! broo..!!

[@mikeearls126]

No Base, Emitter, Collector?

[@sudarshanrao9769]

those 3 are named in bjt not in transistor

[@regale5359]

Those are named in BipolarJunction (BJT) Transistors

[@bypass666666]

Base emitter collector = BJT Gate drain source = MOSFET afaik Also BJT is a transistor

[@csp405]

Not explained fundamentally

[@copernicofelinis]

source gate and drain are terms used for field effect transistors. you are describing bipolar transistors and the terms are emitter base and collector.

[@1tonygunalan]

You tried, but I think I still don't understand. Thanks anyway.

[@Don_ron666]

[@VisionMusic78]

I don't understand anything related to transistors! This topic is so confusing!!

[@jonas8266]

5:15 Well, today Intel is 1985 and AMD is 2018.

[@autogenes]

What does it mean for a charge to be "free to move and carry the current"? What does that even mean

[@Ahmed-Afkir]

Very Very clear explanation Thanks for this

[@mjg1185]

You showed a straight line for a graph of Moore's law, which is a parabola (exponent). Also, you show it going well into the future and Moore's law has come to an effective end.

[@pradyunmore6727]

It is still correct. He used a logarithmic base on the y-axis, so the graph is straight. It certainly would had been a parabola if he didn't do that

[@pradyunmore6727]

It is still correct. He used a logarithmic base on the y-axis. If he hadn't did that, it certainly would have been a parabola.

[@davidduncan9949]

2019 Your explanation of the transistor works is the best one on youtube.

[@edram4051]

Ok. And how do transistors work in those devices they mention at the end of the video?

[@Ryan_Dye-r]

So basically, computer chips / processors / microprocessors are made out of transistors.

hello satis, please help me learn to make animation

[@metalmusic598]

can someone answer this how can the donors give electrons to the n type semiconductor and make that positive when it has an extra electron that would make it negative. If an atom has an extra electron instead of having the same amount protons and electrons it would be become negative

[@SheikhN-bible-syndrome]

Remember that the atom - electron - photons, are all just concepts they are a way of explaining things in order to keep $$$ funding and shut up investors and for the most part these concepts can predict and explain things pretty good but it's not the only concept out their it just happens to be the most popular one at the moment.

[@Promptjock]

The narrator is mistakenly talking about FIELD EFFECT TRANSISTORS (FETs), not BI-JUNCTION TRANSISTORS (BJTs)! "Source", "Gate" and "Drain" are the electrode names for FETs; "Emitter", "Base", and "Collector" are the electrodes for BJTs. The displayed graphic symbol is, correctly, for BJTs. The graphic symbol for FETs is TOTALLY DIFFERENT, especially for "Metal-Oxide Semiconductor" (MOS) FETs. Otherwise, his explanation of "PN Junctions" and their electrical natures is fairly accirate.

[@Mr.Sport37]

Amazing video that even can make students understand, thanks:)

[@elliottsmith8636]

I'll need to come back later, I got lost

[@badnewsbruner]

Yet we STILL cannot make a transistor powered guitar amp that is as good as, or better than a vacuum tube powered amp. The transistor has changed the world, but I still love tubes, at least for audio, there's nothing better. If you've never smelled warm vacuum tubes, you're missing out.

[@nightriders92]

absolutely splendid!! Thanks

[@m4l490n]

Awesome video!! Showed the symbol of a BJT but explained with a FET though.

[@kwiz8848]

By far the best explanation of transistors

[@jeffgibons1540]

WHY DO THESE PEOPLECOMPLICATE TRANSISTORS. THEY ARE A RESISTOR

[@metalmusic598]

No they aint a whole purpose of a resistor is to reduce the amount of voltage coming into a circuit where as a transistor is used for amplifying, controlling, and generating electrical signals a Mosfet transistor is similar to a resistor but is not the same

[@memedaddyio2894]

whats good la tech

[@rodrigomillan8483]

I have never thought about transistors until now, I like old stuff , like the old cars having rev cut out relay, now the diode does the job, and wen it goes out u get new alternator. Thanks for school.

[@GladiusJon]

Can someone please tell me how the gate is switched? Seems like you need a transistor to switch the gate on a transistor. What actually starts the process of adding power to the gate ?

[@joevignolor4u949]

Almost any other device that can produce a voltage can drive the gate. This could be another transistor but it could also be a mechanical switch, a relay, a battery, a transformer or an antenna. These are the most common ones but there are probably a lot of others. Which devices are used and how they are interconnected depends on the application and how the complete device (like a TV, phone or computer) is designed and put together. Overall all the power required to operate all of the individual devices and circuits used to make up the complete device comes from an external power source, such as a battery or a power supply connected to a wall outlet.

[@isq9901]

Yeah, without transistors we couldn't have the unfathomably complex machines known as flashlights.

[@ArifBillahOnGoogle]

*Flashlights*

[@tpmsnewenglandworld6069]

It has the dna.

[@anuarlezama]

I assembled it in a protoboard the motor doesnt turn on, I am meauring voltatage in the transistor when the sensor is on and its not providing enough voltage, in the first pin of the transsitor where the resistance is it measures 4.9, but B is 0.8 and ofcourse the motor will never turn on. What is wrong?
