Hey everyone! Creating videos takes a lot of time and effort. Support ❤️ my efforts by buying me a coffee ☕️! Click the link below.

Thankyou 😊
Dude, keep doing these, please. Im in HVAC school, and you summed up 2 hours or more of reading here.
best explaination Ive ever had of transistors, well done
Thanks
It’s a valve for electrons. Apply a base voltage = turn the spigot.
There, that took a lot less than 3 minutes.
Before transistors, vacuum tubes served the same purpose (but of course were limited in how small they could be made and in their operating voltages). And guess what they were called….
Excellent video on the ( N P N ) transistor, I needed that !
Glad you liked it
luv you for the last rain sensor example..
it was an amazing concept, when water drops on the un connected conductor circuit complets and currents starts to flow through base and working of transistor starts and speakers starts producing sound👏👏👌👌
Actually the transistor turns on when there is at least .7 volts DIFFERENCE between base and emitter this is important to realise
now i want to know how the MOSFET works, great video
Thanks
@1:11-you mean 2 p type sandwich one n type between them. (You say 2 p are sandwiched between 2 n, which makes no sense)
Right after that, you speak of current flow, but don't specify that you mean CONVENTIONAL current. (The electrons actually flow the other way.)
@1:53 you say the high resistance acts like a closed switch, but you mean an open (not conducting) one.
I appreciate your careful observation and constructive feedback. You're correct, I misspoke about the transistor configuration and the direction of current flow. I will make sure to clarify these points in future videos.
The transistor was originally thought as a non starter, being invented in 1846 was far too bulky for any practical use. Having a very large cylindrical tank to hold the electrons with various taps and valves to drain and add electrons as required. In the late 19th century The Clayton steam boiler company of Grandington Ohio would be the first company to use a smaller version but found the main cylinder could not hold enough electrons to operate there heavy equipment.
It's incredible to think about the creative minds and perseverance behind these inventions.
Want more like this!! Come on Bro very nice video!!
Thanks a lot! Glad you enjoyed it. Stay tuned for more!
One of the confusing statements about transistors I heard when I was a teenager is that they act as an Amplifier. and still now after some years of experience I can tell you they're not amplifiers. they're used in an amplifier circuit but they do not act as amplifiers. here's the thing: the transistor has a certain middle-state(bias) between the extremes On and Off states where you can play with hight current side of the circuit (collector-emitter) by acting on the low current side of the circuit (base) Luckily, it happened that the ratio (in/out currents) is linear which makes it useful to produce a higher current version of the low input base current.
Thanks for the clarification!
There is two modes of operation of a transistor. saturation mode and linear mode. In am amplifier the transistor is operating in the linear mode..i digital circuits it operates in the saturation mode
The BJT transistor is a current amplifier. The ratio of the collector current to the base current is the amplification factor of the transistor, which is represented by beta. If the collector-emitter voltage is higher than the saturation voltage, the transistor works almost linearly.
Yup, referring to transistors as amplifiers utterly confused me, as I couldn’t understand how the device itself amplified anything.
And of course it doesn’t, you can make a *circuit* that allows a small applied base voltage to control a much larger current flow, but there’s nothing about the component itself that “amplifies” anything, any more than a water spigot “amplifies” water flow through a hose.
A needlessly confusing way to introduce the device.
Listen to your description of the 2nd transistor...the PNP type.
You fumble when you say that in a PNP transistor, two P type semiconductors are sandwiched between N type semiconductors.
It's kind of like the "One small step for Man..." mistake.
And I know almost nothing.
I was trying to learn the basics here, but that posed a bit of an obstacle.
0:33 i RECKON YOU FORGOT THE S
MOSFET = Metal Oxide SEMICONDUCTOR Field Effect Transistor
Remember , this is a tutorial for people that don't know. so.. don't cut corners and teach incorrectly
I apologize for the mistake. I'll make sure to be more precise in future videos. Thanks for pointing that out!
@@oneELECTRICIAN
YOU ARE FORGIVEN :P
Here is what i respect about you though...
You weren't an idiot about it and you weren't arrogant.
I'm an Engineer (E.E.) and call me pedantic but.. i'm not fussed about things being in their proper place and what not but some things (They don't necessarily bother me) but i will point them out.
Primarily because i'm 50 and i've done electronics since i was 6.
Now i'm a firm believer in a few things
1. If one doesn't care to know electronics or technology, that's fine, You have the right to say . I don't give a stuff and you can say stupid and incorrect things and i won't pull you up on it
2. However, if one MAKES THE DECISION to be in electronics , I feel they should learn it correctly
3. A Person who wishes to be a technical person, even if just for a hobby, should not get lazy about it
4. But then to go a step further (as it pertains to you)
IF A PERSON MADE A DECISION TO TEACH OTHERS ELECTRONICS (to pass on knowledge if you will)
That person HAS A RESPONSIBILITY to pass on the knowledge correctly and for various reasons
- Sometimes incorrect knowledge will result in death or injury
- Other times incorrect knowledge results in a newbie getting taught incorrectly
Now here's the thing, Should a person who PUTS TRUST in your channel (or any channel) for that matter
get taught the wrong thing and then hang onto that incorrect knowledge only to be told down the track they are an idiot and it's wrong what they were taught
NO... I BELIEVE IF A PERSON INVESTS THE EFFORT TO LEARN FROM US
WE SHOULD TEACH THEM CORRECTLY
I've seen many technicians pass on incorrect knowledge to those who want to learn, and it needs to stop because if it doesn't our own industry suffers and so does our passion and hobby.
IT'S GOOD WHAT YOU'RE DOING HERE
But there is a responsibility that comes with it.
Mistakes are fine, But try and correct them if you can
My comment wasn't a stab at you, it was more to raise the awareness of the correctness of MOSFET.
and finally... YOU TOOK THE COMMENT CORRECTLY
too many people today act like idiots when they are corrected, when in fact, THIS IS WHAT WE DO in electronics, we correct each other again and again and again and as a result we learn and learn well.
Today so many people take offense to being corrected (and it is just a correction)
but they see it as a personal attack
SO WELL DONE
- For taking the correction
- For learning from it
IT SHOWS INTELLIGENCE
I like to pay attention to what's going on in this industry that i enjoy and i've never seen your channel before.
Most channels out there aren't that good and god knows we need good one's
KEEP GOING MATE,
WELL DONE
