Even if you are learned, experienced, confident, and have the respect of your colleagues, it's best for you and everyone around you to remain reserved and humble. If you observe something clearly wrong, point out the error by making it a learning experience. You may surprise yourself at what you gain out of it.

The demo with the sinewave is for a TRIAC, for Thyristor it should only include a half of the sinewave (either upper or lower) because the other half of the sinewave it won't conduct...

[bigreddodge]

Just a small correction: TRIACs in dimmers perform phase "chopping" and not phase "shifting". Otherwise, great video!

To be more precise : To switch off a thyristor you have to get the current under its holding current.
Also exceeding the thyristors dv/dt (critical rate of rise of off-voltage) will "activate" the thyristor (mostly unwanted effect that you have to take into consideration). To avoid dv/dt triggering a snubber circuit is used.

I would never have thought of using it in a dimmer. Well, I guess that's what distinguishes the professional from the amateur... Thanks!👍

Thanks for this video. I’ve forgotten this from school. It’s great to be reminded.

[hadibq]

I love your videos, they should be included in electronics schools ❤

[keithking]

A triac and a little "diac" on the gate are used in dimmer switches not tryristors.

The way you pronounce anode and cathode is crazy

thank you, very informative ! keep making nice videos. 😊

[keithking]

Did you hear that word "latch" it will come in handy as you learn more about electronics... But a single momentary switch "on/off" transistor circuit is a great circuit to learn how to make.. 👍🇮🇪😉

[worldwideav]

Many thanks for this informative useful video.
Are both thyristor and triac the same ? please advise, thanks.

[Hopeless_and_Forlorn]

The light dimmer is a normally effected by a triac, not SCRs. Also, in sixty years of electrical work I have never heard of an aNODE or a cathODE. Please explain.

Electricity travels from negative to positive! That is a fact! Forget the dead.

[petevenuti]

So it's closer to a mosfet then transistor or diode? Does it also have capacitance in the conduction channel?

[Blackdwarff]

I Gained a Knowledge again Thanks Man 😅

My Great Aunt had a tumor on her thyristor. Big ole' lump.

[goodwill]

on the end you show full sine wave. Not sure, but could be that theristor works only in one direction and gives only half wave. For full sinewave you need Tirac.

Thanks for explaining how thermistor works.
