A natural teacher! I have been looking at diagrams of doped and undoped silicon and reading the description of what is going on inside that chunk of silicon for over 40 years. Usually I have ended up thinking "Ok, I am going to have to take your word for what all those electrons are doing in there." Finally, four decades later, a little imaginary guy with a variable resistor gets me to understand. OK, there was some fancy narration going on to, but THAT analogy is what opened my eyes. Its OK I won't sing "Amazing Grace".
I remember a sketch with this little guy inside the transistor from a German electronics journal in the 1980s when I started to get interested in electronics ;-)
I hope you get into operating Voltages and configuring the Base input Resistor for its saturated Voltage, the Collector input Resistor for its saturated Voltage, and the Emitter output Resistor for its saturated Voltage when needed.
Hahaha the guy spends his live in a transistor doing multplicatin by 100, then be killed by some human making short cercuits not who gives no care becouse they can cheaply replace it and doing it again..... 😭😭😭😭
Sometimes I want to learn something, and sometimes I want a nap. I usually don't know which is going to happen, my intention is always to learn, but it can go either way. This is about me at the time, the content usually has no bearing on which is going to happen. I read someone mention Bob Ross in a comment, that is exactly what I am talking about. If you start calling electrons "Angry Pixies", it may be even better! In other words, I love your videos and your presentation. **edit - mistyped "electrons". I typed "elections". Elections are also angry pixies.
Very nice. If you limit Ib you should reduce Ic and the guy inside the transistor would be wasting his time trying to turn the resistor up, in other words, you would save Power.
In this case there's 5 volts between the base and emitter. I believe that is okay as the datasheet says BE can go up to 6V, but usually you would want a base resistor yes?
The collector will respond very quickly to changes in current in the base because this relationship is driven by quantum mechanical effects between the atoms and electrons in the doped silicon that makes up the transistor itself. However, there are capacitances created between the base and emitter as well as the collector and emitter as well as other parasitic capacitances. The combination of all these cpacitances will dominate the transient response time of the transistor.
Isn't it counter intuitive to say a transistor is in cutoff when it's letting nothing pass and saturated when it's letting everything go through. You would think that the resistor would be saturated when it's blocking everything it can no? Or am I missing something? Sorry noob over here
The transistor is in in "cutoff" when the collector current is "cut off" (i.e., no current is flowing through the collector). The transistor is "saturated" when the transistor cannot produce any more collector collector current at the given base current and collector-emitter voltage (i.e., increasing the collector-emitter voltage will not change the collector current). The term saturated actually is drawn from the underlying mechanism that makes a BJT work, in this case the transistor silicon is saturated with charge carriers (i.e., the transistor cannot physically support any more charge carriers). The amount of current that a transistor can pass is directly related to the number of charge carriers available in the silicon. It is good to keep in mind that a lot of the nomenclature around transistors (BJTs and FETs alike) is derived from a quantum mechanical description of how the device functions which means the names can feel counter intuitive when thinking about how the device operates from the perspective of conventional current flow. (I mess up drain and source in FETs all the time because they are simply backwards as when thinking about conventional current flow.)

This is by far the best explanation of a transistor function I have ever witnessed. Great job simplifying a complex component.
The light over my head finally turned on, regarding transistors ... nice job and thank you!

Transistor man from The Art of Electronics?
Again, very well explained. 👍🙂🏴
I always knew there were little men inside my computer. I hate when they go on smoke breaks.
Nice use of the ultimate teaching tool: colored chalk, or digital ink as the case may be.
I hope you get into operating Voltages and configuring the Base input Resistor for its saturated Voltage, the Collector input Resistor for its saturated Voltage, and the Emitter output Resistor for its saturated Voltage when needed.
Wait a minute? There is a little guy in a transistor? Now I feel bad thinking about all of the people I've killed 😞
Ryan Jardina if you watch rick and lorry then it’s not really surprising
What’s rick and Lorry?
Hahaha the guy spends his live in a transistor doing multplicatin by 100, then be killed by some human making short cercuits not who gives no care becouse they can cheaply replace it and doing it again..... 😭😭😭😭
He most likely wouldn't care if you kill him because he's bipolar.
@@ThisWasEpicness is that the one with the pickle man? very funny show
This is so good❤

i have to watch sp,thing else to get ti sleep, i get drawn in by his explanations lmao
Thank you very much!! Great video!!!

6v is max emitter-base voltage, not base-emitter voltage.
What kind of probe ar u using for your multimeter
great video. thanks Ben. question: how fast does a transistor react to changes in the base current, surely there is some delay right? thanks
The collector will respond very quickly to changes in current in the base because this relationship is driven by quantum mechanical effects between the atoms and electrons in the doped silicon that makes up the transistor itself.

I'm thinking the same thing. How can we contact Ben for confirmation ?
I watched again, Ben was right.He was saying current , not resistor.

Natural burn reacher)
ethical explanation makes much more sense you shouldn't have simplified it
