Great video. Capturing the basics in clear and simple terms. thank you

Man! I was losing my mother lovin mind trying to figure out some shoddy wiring. Your video helped me to just rewire it properly, thank you sir! 🙏

Great explanation! Thank you very much.

from ac supply they produce dc and convert to ac again by inverter?. is it so?.

2024 TIP! MAKE SURE TO WATCH THE VIDEO AND IN THE DESCRIPTION THERES THE TRANSCRIPT AND KEY CONCEPTS. YOU CAN WRITE IT ALL DOWN AND READ IT THEN SEARCH IT IN THE TRANSCRIPT WHEN YOU WANT

Hey! thank you for this great video. I'm looking into installing a PID controller on my espresso machine (my background is not in engineering) so this really helps me to understand the parts needed to make the controller to work. Thanks!!

Here in Brazil electric showers are the most common, and you'll be surprised of how few homes have residual breakers. Thankfully, copper conducts electricity better than water lmao

🙏🙏

I think you were little bit tired or not enjoying while making this video 😂

Why did the human resistance on the multimeter show 300 kilo-ohms but when you did the math in the next clip to show current running through someone you used 1.5 kili-ohms

Super 😍

great video! Clear explanation thank you. And bonus points for using an angle grinder for cutting a pen casing - you have to admire that kind of overkill - love it :)

Hi there! I have seen relays at my workplace. We typically use them in automation. We have heater banks in AHU and we remotely operate them via SCADA/CMS. So the command signal is sent to the relay which then provides the power supply to the heater bank.

Wicked video! Love the format and pacing. High quality.

Thank you this really helped me

lol why americans have those old tech breakers ?

I see you used silicone carbide as compound for blue LED, when it's actual indium gallium nitride (InGaN), SiC is only used as a substitute, but InGaN is industry standard.

So if i put a 12V input and 5V on the gate pin, it'll only send 5V through?

5 sec

I think the resistor should be before the LED to make sure that it takes the right amount of power

Best Video I have seen in a while, so good explained and detailed :)

I'm not watching this for school I'm watching this because I fuckign love engineering

Thank you for this, I have just self diagnosed my car issues that have been plaguing me for months. It's the bloody alternator. Cheers

Well, they do not protect people from getting electrocuted, but from getting burned by the fire spreading.

Great video! I recently encountered an issue with my autoclave where the tube that releases steam was pressed against the back of the collection bottle. This seemed to cause a weird clicking and grinding noise. I suspect it was because, during positive pressure, steam was released without issue, but during the negative pressure phase, the solenoid valve struggled to pull the negative pressure back in, resulting in those noises. Has anyone else experienced something similar or have insights on whether this explanation makes sense? I adjusted the tube's position, and it seemed to resolve the issue. Would love to hear your thoughts!

Mosfet (Positive to Drain, Negative to Source) N-Channel Enhanced = Normally OFF = positive to gate to turn ON P-Channel Enhanced = Normally OFF = negative to gate to turn ON N-Channel Depletion = Normally ON = negative to gate to turn OFF P-Channel Depletion = Normally ON = positive to gate to turn OFF

does the gate when charged up slowly discharge and the mosfet switch off eventually?
