Why not start with the info 3:29 that it's a thermal sensor output? Or have it in the title? At least as a teaser, but I appreciate truly the really short and informative video! Thank you <3
This logic is incorrect. You stated that current will go out of both paths and that the amount would be reversed to the capacity of the resistors and showed how the lower resistor passed a more amps that the bigger resistance as evidence BUT this is expected. What you have is simply A + B = C… if you have wire with 500 ma and a 50 ma then you should see 450 ma out the end of the wire. The same is true of the other wire with the bigger resistor.
This is kinda great idea !
Well I wasted by joining in a college for engineering,I could just use yt to learn more way deepr and interesting with a better understanding
thanks about the last one specifically
Ничо не понял. Это канал Major Tom Workshop на английском?
what about relays ?
When the LED heats up, the current increases. This is the normal behavior of semiconductors of any type, just as the gain of silicon transistors increases, not to be confused with MosFets. The situation there is completely different. The resistor is only there to limit the current, which is 0.025A for a regular LED, i.e. 25ma
what power supply is that @Ronmattino?
I wish these videos were longer
Is two different voltages meeting at the transistor and outside emiter has no effect to batteries or circuit short?

Holy shit. You just made me discover what Windows calculator can do. HOLY SHIT.
Nice explanation 👍
Bro explain my 3 years of personal, research, library books, reddit posts, google page 3 searchs, in 1 yt short💀
I Gained a Knowledge again Thanks Man 😅
Wow
What is this faraite
Aww... must you go and spoil all this!? I wanted to continue to entertain people with this conspiracy theory. Now everyone will know!🤬
I use a fly back diod and flyback capacitor on my motor control circuit
I thought zener diodes work at 0.7 V? Why does this one need to go up 2.35 V?
Thank you, sir.❤
This is great education..adding information on applications would be a great attempt
Remember: Capacitor Stores Voltage Inductor Stores Current
I get some of this but the breadboard medium it what does so. I'll build a circuit all day with a datasheet tho 💪✨🎸 (ima leave this here)
Best explain
best,best,best
Why this video has 1.5k views😭😭😭
Excellent ❤❤
этого видео нет на русском языке?
Make more basic videos
TIL, that ROM isn't memory drive😂 So then, what is Cache in Cpu? And how come it's retain info of my last password even after ram got wiped(restart/warm boot)?
Большая мастерская Тома)))
this is very far from "all"
Instead of diode and all that ON/OFF circuit, a simple transistor (BJT/MOSFET) could have done the job. Also I don't think this is going to work like intended.
Lise bir elektronik derslerinde bu kadar güzel ve basit anlatılmamıştı diyotlar. Süper anlatım 👍
Walter ahh cable
Best visualization ever...! Great job!
I know
So what’s the difference between an SCR and a thyristor?
Never seen something like this best and very simple video about bridge rectifiers 🎉🙌

Relay does same thing
Could u justify Why magnetic monopole doesn't exist🧲??
👍👍
could u explain the neutral part more in debth please. Like how it works and why it need to have a common neutral as opposed to a separate netral of its own for every phase? cheers
Basically, because having a separate neutral for every phase is redundant, so neutral is like a common wire for all 3 phases. So, it's 4 wires instead of 6 wires.
The cool thing about capacitors is after they have been charged and then discharged, they call bounce back to the charged state without being hooked up to a power source
This totally misses the point why 3 is so much better than 2 🙄
I mentioned better efficiency.
@@RonMattino you are basically stating that the sky is blue without explaining why the sky is blue. The real reason is two fold. 1. On a balanced circuit, you can eliminate the neutral wire as it has 0 current. Basically you can transmit 3 times the single phase power over just 3 wires as the other 2 act as return at any given time. 2. 3 phases create a rotating field which greatly simplyfy the motors using it. A Single phase motor on the other hand, requires a capacitor to shift a phase in other for the motor to start spinning. A single phase motor also has minor vibrations due to the dead times in the cycle.
2nd
Would 4 Phases be even better?
No because you then need to route 4 (4*Ph) and 5 (4*Ph + N) cables everywhere, which will increase the cost significantly, for no benefit.
@@deang5622 Alright, makes sense
