That was the best explanation I've heard for a transistor. That was one component we didn't learn about in school and it has proven quite useful in playing with circuits nowadays.
It was decent but it missed out on a heap of what transistors are used for, when they are used on their own. The video only deals with transistors acting as a switch (as you would see within the processor in the device you viewed the video through) but they can also be used as amplifiers (seen in the sound generation area of your device). They are so much more interesting within that context, than as switches.
@@pleaseelaborate3163 in the electrical engineering classes I had to take for a computer science degree. We learned digital logic, including making circuits on breadboards, but never used anything more than wires, logic gate chips, and the occasional 7-segment display.
I have to say that's one of the best explanation of transistors, with this explanation one can slowly but surely build up their knowledge in what is arguably the most important electrical component of our time
wow I know this is Crash Course, but if you just left tiny spaces in between speech segments (as would happen in normal conversation), I think it would vastly improve comprehension - at least for me, but likely for others, too. there is no pause in which to process that I have understood something before moving onto integrating a new concept.
Note that processing Silicon on an atomic level was described in this video however, the terminology describing the process of adding Boron or Phosphorous to Silicon called "Doping" was not correctly identified.
I studied in a basic physics course about how a solar water heating device works. In this video, you just explained the behind-the-scenes of a solar panel. Thank you!
Anything computing uses unipolars, because controlling by field, not current, but I get you'd need another video for explanation of those. Also, FULL BRIDGE RECTIFIER, and from now, EVEN FULLER BRIDGE RECTIFIER and THE MOTHER OF ALL FULLEST BRIDGE RECTIFIERS.
This is such a good video but it’s too fast like you are talking at 1.2 speed. Then you’ll make a really important point and instead of pausing there is a video cut to immediately launch into more information. I realize it’s a TH-cam tradition to eliminate all natural breaths and pauses but I think it’s a bad tradition.
Please add any suggestions.

When the arrow on the circuit changes direction at 9:14, it changes from saying Electron Flow to Current. This is just to show that the two terms are opposite notations, so the flow didn't actually change directions right?
@@MrGustaphe She refers to a npn Bipolar Junction Transistor which DOES REQUIRE a "gate current" (which is applied to the sandwiched p-type base). You are thinking of a MOSFET which is controlled by gate voltages or more accurately, the differences in applied potentials. MOSFETs still do require a tiny, usually insignificant, amount of gate current to create the potential difference.
Apart from the good explantation on this major subject in our current society I must say......What a stunning woman. Knowledge, eyes, mouth and hair fitting perfectly in her smooth face. I think I will stay on this channel.
Your videos are awesome, and these videos were the reason I passed my physics final. Have you guys considered partnering up with the AAMC to make videos geared towards MCAT review?? I would love to watch your videos to review for that content
Jesus Osegueda yes but I'm talking about the amplification use of transistors, you need it on the output but I don't think it is important on the logic operations
@@xspager Sure it is. For example, you can make an AND gate by putting two transistors in series, and it will only allow current to go through when both transistors are switched on.
Woohoo, this is a really good class on BJT's (Bipolar Junction Transistors) and MOSFET's, and solar energy. And I really like this girl! She is so skinny and tall and smart! Maybe she can talk about the "small signal model" next time! If your are as cool as I am, do the "small signal model" next time and what the larger and complex reality that this model represent! Gracious, gracious, gracious!
Well, there are also other atoms than can be (and are) used to to produce n- & p-type material. Also, why do you find that confusing? I feel like (n)egative and (p)ositiv are very clear (ans simpel) words for what is going on.
9:30 you didnt explain where the electron goes. you just made up a force and called it electricity so you didnt violate thermodynamics and ended the lecture! also, that was the worst explanation of how a diode works ive ever heard! i didnt even know you were describing a diode until you said it afterward!

Quick reminder to everyone wanting to ask about Marie Curie, one of her Nobels was in physics, the other was in chemistry.

This is one of the best explanations on solar cells (in a 10 min video) that I have seen so far.
This episode was more helpful than my classes.
I watched the entire series in a afternoon,dang learned so much thank you Dr. Shini Somara and crashcourse. I love to hear you talking
I understood like half of this. I hope someday I can understand this completely
I study renewables and just had a test on PV last week.
Well explained!
diode bridge? FULL BRIDGE RECTIFIER!!
🤣
why is a steam engine powered by a solar panel????
Maybe that's the joke?

Or they could put a big dot on the bottom right-hand corner of the screen once an idea or idea set has been exposed, so we can pause if we wish.
Been waiting 22 episodes for this to show up haha.
Note that processing Silicon on an atomic level was described in this video however, the terminology describing the process of adding Boron or Phosphorous to Silicon called "Doping" was not correctly identified.
Wow, what a great episode! Semiconductors, transistors and solar power explained
Semi conductors are great for making our lives easier.
I studied in a basic physics course about how a solar water heating device works.
In this video, you just explained the behind-the-scenes of a solar panel.
Thank you!
I love this so much!
no
she is not good ok
Great job, great video, well explained.
You are now reading a meta comment in the comment section commenting on the meta comment at 7:10.
Now that's (insert reaction statement, preferably a pun)
(more strained pun)
Do one on motors and generators
Mind Blown!!!
Transistor and Semi-conductor
Anything computing uses unipolars, because controlling by field, not current, but I get you'd need another video for explanation of those.
Also, FULL BRIDGE RECTIFIER, and from now, EVEN FULLER BRIDGE RECTIFIER and THE MOTHER OF ALL FULLEST BRIDGE RECTIFIERS.
I wish these showed up in my subscription box
Thanks for posting the resources!
super informative
Does this channel provide any "Try this at Home" Experiments?

The transistor mentioned is a BJT Transistor, not the more commonly used MOSFET Transistor.
THANK YOU!

so good
Did anybody else hear "Second was for describing a way that SuS materials can conduct electricity with no resistance"?
This is amazinggg
You don't need to dope silicon to make it conductive. That is just done to change the band structure. Silicon by itself is a semiconductor.
And you don't need a gate current in a transistor, you need a gate voltage. That's the large advantage of transistors over radio tubes.

You're right. I've been spending too long in MOSFET land.
@@MrGustaphe Cool, cheers to MOSFETs controlling almost everything we have today
You can work and research Semiconductors and solar cells materials following the career of Electrical or Mechanical Engineering.
i love that, 'to do:make meta reference in episode so people in the comment section comment on it' lol :)
Guys why are the holes in the P type not cancelled by the B type?
Amounts of P and B doping can be different, so there would remain holes or excess electrons. Also, P and B don't move, but the electrons and holes do
Early notification squad, where ya at?!
They busy studying
Why don't we use sulphur in n type semiconductors for better current or do we?
What do you mean better current?
What? 10^-9 up next? That's like, a crash course cliff-hanger

That's weird comment

make a crash course on narcotics
Yay first comment! Thank you for making these videos! They are awesome.
im commenting on that meta reference btw
7:10 anyone notice that notepad by the laptop? Thats a weird way of spelling "make a pandering joke".
it says meta reference
Alem Alem 😐😐😐
I want to convert sun energy into electricity ? how is this done???????????????????
Radioluminescent paint? 🎨🤔🤷♂️
i have no idea qhat you talking about
Solar cells.
All seem foggy
Hey
Lot of talk about holes waiting to be filled in this video.
She talks much slower in this series than Physics series. Those Physics ones are all a mess!
that statement around 7:02 makes no sense, the ability to use a small current to control a large don't have anything to do with zeroes and ones
Is there a current? That's a 1
No current? That's a 0
Jesus Osegueda yes but I'm talking about the amplification use of transistors, you need it on the output but I don't think it is important on the logic operations

ALBERT EINSTEIN NOBEL PRIZE not mentioned.
wtf showing a power regulator as the objekt in focus when you talk about transistors?.
Let's be honest, it would have made more sense to call them B- and P-types, considering P also stands for phosphorus and is needlessly confusing.
Except that sometimes other elements are used to create N- and P-type semiconductors, such as Gallium and Arsenic.
Well, there are also other atoms than can be (and are) used to to produce n- & p-type material.
Also, why do you find that confusing? I feel like (n)egative and (p)ositiv are very clear (ans simpel) words for what is going on.
Fritschge128 I’m thinking he was making a joke lol
Not confusing imo
Its so basic
