Finally, I could understand WHY we must NOT to use a Triac to drive DC current... Thanks a lot! Greetings from Argentina!❤

Thanks! I understand triac clearly from your easy style of explaining! I was always confused about why triac can go ON but can't be turned OFF in DC use!

For years I have read about triacs, not really understood, and then forgotten everything I've read. Finally now I understand what they are!

Hello, nice video for beginners but there's a lot more to know when using triacs: - snubber networks for protection, - zero crossing switch to reduce electrical noise generation, - a lot of other things to consider 😁

Thanks! Finally a triac video that just "clicked" for me. 😊

Thank you for your videos

a good explanation brother...thank you

I love the bird on a transformer example for danger. It’s hard to not understand that regardless of what language or dialect is used.

Great video for beginners

super useful, thanks !

Great video. Thank you for the explanation. Currently reading about SSR and this gave me a better understanding.

Thanks for this presentation and many others like it. Slowly but surely I am piecing together electronic components, their uses, and characteristics and interactions. Self taught, but for presentations such as this. Priceless.👍

To turn on/off an AC appliance (like a light bulb), of course it's much simpler to just use a *relay* which can switch both AC and DC loads. The only real purpose of introducing a triac to a system is to clip the AC waveform and provide throttling which is a super useful function. That could have been made clear at the beginning of the video.

Nice one.... this is the simple reason we can plug the power into the socket either way. I wondered but never really investigated. How awesome!

You will be 500.000 folower soon. 🙏👍

ممنون مهندس ، عالی بود ❤

Thanks!

Much obliged.

Thank you mr wizard

hope you will upload a video explaining how to check a TRIAC with a multi meter. and how to identify them with other equal items. Thank you very much!!

That was awesome 👍

Perfect sir

You didn't have to electrocute the bird, we believe you 😅💔

عالی بود .... یکم بیشتر توی جزییات وارد بشین لطفا .

Damet garm. 3 degeye avvale filmo ke didam fahmidam yeki as behtarin amuzeshas. Karet kheyli aliye. Keep up the good work bro

Nice also make zero cross detector video 👍

Nice video! How would you quickly test a triac with a multimeter?

How did you decide 100 ohm resistor between opto coupler and gate of triac?

Hi, thats grate. Thank you. One question, I try to turn on and off a water based cooler motor ( an AC motor that start with 10A and continue with 2A load) with BTA-140 triac and moc3021, I also add a snubber circuit. every thing work fine and I can switch on and off the cooler at first, but when cooler working for about 20min BTA-140 getting hot and it did not disconnect the cooler switch(did not turn off the cooler) any more 😢. any idea or workaround about this issue ?

لهجه قشنگ فارسی میزنه 👏😉

Can multiple be paralleled like MOSFETs for additional current capacity?

خیلی عالی بود ممنون من سعی کردم برای کنترل موتور کولر از ترایاک bt139-600E و moc3021 استفاده کنم اما به دلیل نزدیک بودن پایه های ترایاک هنگام روشن کردن موتور جرقه میزنه و باعث سوختگی در برد میشه. و عملا مدار قابل استفاده نیست. پیشنهادی برای حل این مشکل دارید ؟

im trying to use a triac paired with an arduino to control the direction of an ac motor, how would i go about this?

When you dim an halogen 100-watt light bulb with a dimmer, is the power consume always 100 watts?

Do you have another channel

Since you're using optotriac to gate the large triac, does that mean your large triac is turning on and off every time the AC current changes direction? Why not just use an optoisolator?

How can dimming a incandescent bulb using Potentiometer isolated

ایشالا مثل الکتروبوم میترکونی یوتیوبو

Touch the Triac when the circuit is live? Crazy to touch Mains Voltage? 7:45 OK, you only have 120V AC and 170V peak. In Europe these are 240V AC and 340V peak. That bites you hard in the fingers! This can lead to cardiac arrhythmias or death. If you're lucky and just fall off a chair or ladder and break your bones. If things go badly, you can no longer pull your hand back and can't cut off the power. In Europe, the rule is to set it up safely, then take your fingers away and switch it on. Don't touch it never while it's hot ! Never or you'll regret it or it is to late !

Why isnt it working for me😢

so basically if we try to use the triacs in DC applications, it is literally like using a thyristor and we lose the point of using a triac

Great, let's all put mains AC through a breadboard. No bad things will ever happen. Seriously, puting 120V AC through a breadboard is a very bad idea. Stay safe guys.

That's very sad. This bird is probably death. High current flow thru his brain. Sadly many birds get electrocuted every day.

Thanks
