Why electrolytic capacitors are actually kinda crappy 💩
Electrolytic capacitors are common, but knowledge of their limitations is uncommon. A demonstration is shown highlighting the difference in performance between electrolytic and ceramic capacitors in power supplies. Other topics discussed in the video: Electrolytic capacitor construction, ceramic capacitors, ESR, ESL, impedance curves, why "0.1uF", and more.

Excellent content Thank you!!!
In the thumbnail you can see the diode is directly in the arduino. I would recommend using a breadboard as it does not require any soldering or bending wires.
why is 512 half? 0-1023 is still 1024 numbers. It should be 511
W w wwww www Winamp Winamp!
1:10 - 😂🤣😂🤣😵🥴😂🤣
The Dillon reference 😂
Thanks.
Wait what was that last part about i could die?
its not overclock, its just overvoltage
Insane explanation, best enough to clear out doubts
I guess the ram has amnesia now
i am very interested in the video you said you made that shows how to create a DC output from a PWM input. could you please share the link?
Great video BTW
ua-cam.com/video/OBM5T5_kgdI/v-deo.html
You just answered a bunch of questions I had in only 2 minutes. Thank you!!!
I can't believe it just a burning memory.
If you use it outside, does the sun interfere with the signal?
*if you overclock a DDR 2 RAM*😂
Nice explanation, thanks.
True. However I'd like to use N-channel-MOSFETs with their lower RDS-on and cheaper costs. Any idea?
You can do it with an N fet on the low side in a similar way just be aware that the resistance you are introducing on the ground path can cause problems in some circuits
6:19, I wish I could thumbs up twice lol.
There’s a lot of stuff in arduino. I should know, I’ve trolled enough of them. But as others here have said, this is an excellent tutorial. Thanks for all of these videos, I know that as I watch them I’ll learn loads. Greg
Heartaches, heartaches...
Ewel ozem uitholen gok me der bie bezig Oeden
Actually when you break the inductive current, energy starts moving in d-s capacitance of mosfet increasing voltage on it. You can demonstrate it using mosfet with higher current ability and therefore with bigger capacitance or add external capacitor across d-s, the spike becomes less.
12 years!!!!!
We want mexican wave
Thank you
This over voltage add resistor
the torture of a ram stick for their crimes
❤❤
❤❤😊
Protogens : ☹️☹️☹️☹️
Best emoji used awesome
Could you please explain to me how to physically connect all the grounds together? I'm a newbie, and can't understand which wires go together, even when looking at the breadboard. It's very confusing.
Memory went from RAM to PTSD real quick.
Thank you so much🤩, your video is really helpfull and meaning full with each and every word of defination it cleared all my doughts and difinations with mathematical formulas
You brought me into the beautiful world of electronics Made my teenage years awesome And you suddenly vanished Come back Afro 😔
That's a real it's just a burning memory
Wow i was 25 when this video came out lol time waits for no one 😢
Its like x4 zoom ? :/
Better then greatscott
A good looking ARDUINO is sign of a master. But a beat up A#DUINO is a sigh of expert
what my mom thinks will happen inside my house when i turn flicker my lights
⭐⭐⭐⭐⭐Great !!
Thanks for making this video. Would it be possible for you to make a video on unregulated DC power supplies for high current low voltage linear amplifiers used in 2 way radio?😀
Very good content, but the vocal fry is painful to listen to.
i tried it. it works. this is amazing
That is just wrong 💀 There is NO WAY u just charged an alkaline battery
