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!
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?🙏🙏
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.

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...
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
Superb animation, easy to follow.
Its really a good explanation both visually & conceptually!!♥️
Thank you
Whyl only 70k views, this is masterpiece
so the transistor works as an amplifier by being a super fast / efficient switch.. *mind blown*
Really wonderful pls upload lots of videos pls pls 🙏
Good job
Really useful god bless you and your family 🙏
Hello, why does electrical flow comes from the Plus terminal of battery instead of minus?
It's convention. In reality electricity is the flow of electrons, from negative to positive terminal.
Between your head and butt which part are you thinking from??
@@markadadofficialactually, hes right. Electricity flows from negative to positive on a battery.
Electrons and current flow in opposite direction
Amazing. Thank you so much.
Awesome video thank you

Thanks for the video!
Resistor is a load in this circuit..
Very nice thank you❤
You're welcome
Very infomative
Isn't the collector only moderately doped?
No. Collector collect 95% of the incoming charges,therefore it need to be heavily doped.
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?🙏🙏
thank you;You Beuty 👏👏
pure excellent, thanks
I love it thank you
in the video b\w 2;50and 3;30 seconds //the Emittor isn't reverse biased/ explain plz plz'???🧐🙏
Going to bed. Tired. Tomorrow I will explain, don't mind.

Great
Good

Current flow is of two types. Electronic current and conventional current.
@@Janvisualphysics if it flows to the battery out of the transistor the speaker will not make a sound...
@@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.
