Better explanation than I got in hours of lecture from a tenured professor. Well done!

[@techtimes1985]

Superb animation, easy to follow.

How do photo cells work ? Great educational videos .

Hello, why does electrical flow comes from the Plus terminal of battery instead of minus?

[@Janvisualphysics]

It's convention. In reality electricity is the flow of electrons, from negative to positive terminal.

[@markadadofficial]

Between your head and butt which part are you thinking from??

[@unosquash]

​@@markadadofficialactually, hes right. Electricity flows from negative to positive on a battery.

[@korirkipnisden]

Electrons and current flow in opposite direction

[@heph4estus570]

Who even uses electron flow nowadays bruh, majority of books and even circuit design is in conventional current flow.

Thank you

Q1: Why do we need that resistor? Or put differently: what would happen if we removed it? Q2: What decides how high resistance that transistor should have? Thanks for the video!

[@bidhanlohani-uy5wj]

Resistor is a load in this circuit..

[@senthilkumarsenthil832]

Really useful god bless you and your family 🙏

[@kitkirkyen2002]

Amazing. Thank you so much.

[@jrc1156]

so the transistor works as an amplifier by being a super fast / efficient switch.. *mind blown*

[@faisalahmad812]

thank you;You Beuty 👏👏

[@ishikaghosh1028]

Its really a good explanation both visually & conceptually!!♥️

[@senthilkumarsenthil832]

Really wonderful pls upload lots of videos pls pls 🙏

[@vahidfarzi376]

Very nice thank you❤

[@Janvisualphysics]

You're welcome

[@Smegma_pirate]

Awesome video thank you

[@Ishtiaqabbasi1982]

Very infomative

[@serdar-ors]

pure excellent, thanks

[@SnifterRoux]

Isn't the collector only moderately doped?

[@Janvisualphysics]

No. Collector collect 95% of the incoming charges,therefore it need to be heavily doped.

[@betheljw7416]

If the collector is heavily doped as you suggest.. won't it (collector)get heat up as more electron are injected from the emitter? What's about the breakdown voltage too?🙏🙏

[@bennylarussa8010]

Good job

[@FazalMola-ur8ns]

❤❤❤❤❤

[@FelixDavura]

I love it thank you

[@faisalahmad812]

in the video b\w 2;50and 3;30 seconds //the Emittor isn't reverse biased/ explain plz plz'???🧐🙏

[@Janvisualphysics]

Going to bed. Tired. Tomorrow I will explain, don't mind.

[@sabarasoolrasoolbux2679]

​@@Janvisualphysics explain plz

Npn transistor is connected to batteries. On input side, Emitter ( n type material...negative ) is connected to the negative terminal of small battery and base ( p type material....positive) is connected to positive terminal. This makes emitter base forward based, baising means the way you make connections. On the output side collector (-) is connected to the positive terminal of the large battery while base (+) is connected to the negative terminal. This way collector base is reversed biased. For a transistor to work as amplifier, it is necessary to make emitter base forward biased and collector base reverse biased. I hope this was helpful. Feel free to ask if you still have any question.

[@koenvandemoortel2206]

Liiks nice but misleading: the image comparing a BJT and a MOSFET suggests that the first is small and the second is big, which is wrong; you show a small power and a big power transistor (which can be BJT or MOSFET). And nobody ever puts a battery on the base like that; that's confusing.

[@WabuhWabuh]

this is not the proper flow of electrons...it is reversed & goes to the mic first the mic signal is coming from the negative end...and fed into the collector of the transistor....out the emitter...this video has it backwards...

[@Janvisualphysics]

Current flow is of two types. Electronic current and conventional current.

[@WabuhWabuh]

@@Janvisualphysics if it flows to the battery out of the transistor the speaker will not make a sound...

[@WabuhWabuh]

@@Janvisualphysics that's just bullshit science...dc current flows one way

Easier to understand when applied to plumbing eh. Then be a heating engineer instead.

[@mohamadfazli5575]

Lady you couldn't explain transistor works and it works? Other word you couldn't explain why it works ? How a transistor boost and impllofy the current? It seems that you don't know it yourself, otherwise you would have explained how and why it works , understand? Please reply
