thanks sir...
Nice video please provide limition of tric
Hi, what is the normal gate voltage range of TRIACs for triggering via micro controller. Should the gate voltage be DC. Eg like MAC97A8.
Very nic sir 😊😊

Helped me a lot
Sir triac is also used in split ac pcb for blower motor speed control , there i found blower motor working directly without gate trigger voltage, what would be the reason? I changed triac also but condition is same .I removed optocoupler still motor runs, Please advise.
Can u a lecture on silicon bilateral switch
We need some important points also that will useful.....
Sir input source dc or ac?
Nyc one sir but thodi theory bhi mai jaise triac vo pura bta da karo
I have question sir,
How can I use BT137 or BTA16 to control 220VAC lamp, how much the gate voltage and current should be ?
nice to explain
Your welcome
Nice
Sir, U can show a model of each device along with the video, so that it may be more clear for us to understand the structure.
I will take this suggestion for next subjects
Engineering Funda thank u sir
More explanation is needed
See another video based on modes of triac
Hi sir..Is TRIAC acts like a diode and two transistors?
Thank you so much

Good class
Can you also explain SUS = Silicone Unilateral Switch??
What charecteristics are taken into consideration while selecting a Diac to trigger a Triac?
Both are bidirectional device
thanks sir

I am trying to repair and troubleshoot a SCR which is used as exposure switch in an X-ray unit. Here 230 V (AC) first is fed to primary auto transformer and then stepped upto 150KV (AC) using secondary transformer and further rectified to pulsed DC to run the x-ray tube. My question is if this SCR is unidirectional, then how this SCR switch is used in the AC line between primary and secondary transformer. Theoretically SCR switch should be used in the rectified DC line.
👌👌👌
Sir make videos according to government exams
I will be beneficial for both of us
Will u give detail explanation about triggering modes of TRIAC
It's there in my playlist of power electronics
Great
Your welcome
plz make a video on p i d controller
It is there in my control engineering Playlist
Sir what is the transition state? Please give me note about it..
Ossum notes sir 👍👍👍👍👍
roshni ji u r also r u preparing for something
Sir please briefly described, working principles, functions of Multivibrator, OPAMP by some provided videos...
Nice lecture. But ye agar thoda hindi me hota to bahut jada achha hota
One Simple like and comment is not enough for this channel.
You saved my Ass. Otherwise Good know what will happen with me ....😀
Thank you so much sir , doubt clear for ❤️
Love and happiness of students is my ultimate goal, God bless you 🙏, keep learning and keep progressing.
@@EngineeringFunda welcome sir 🙏🙏🙏
👍
your welcome
Could u please teach 4 types of triac
I won't able to teach....
it should be explain more
Why the voltage decreasing in scr above the breakdown voltage.what happens inside scr at the time
Because after the Breakdown, If you apply a small voltage the current will increase rapidly,as the depletion layer has broken down.
Where it available sir please tell me
Sir how can I will explain it's operation ckt diagram and vi characteristics in exam
Is the TRIAC having an bidirectional voltage bloking capability...????
sir can you explain the 3rd application of triac that is utilize in cooper ?
nilesh verma
It's use in ac chopper
Thanks sir. Sir I have one question. Do I should understand SCR first to understand clearly TRIAC?
Yeah
Explain also modes of triac triggering
Separate video is also there on it
Tnks
sir i have seen some of your videos and i have understood everything . in your scr videos i your teaching should be improved
It is better way if you explain how TRIAC used in given application
Can i trigger the gate with higher voltage than its rated voltage? For example( if i need 12v to triger the gate but i apply 20v in it what will happen?)
Trigger will happen but you may damage your thyristor
100/100
Sir mt 1 mt 2 are which type of terminals like in scr there are anode and cathode so what is mt1 and mt2 ???
It is bidirectional
Sir u said that triac is back to back connection of scr then what about diac..?
Diac is back to back scr with gate is been grounded
Ya triac is back to back connection of scr with gate terminal and diac is also back to back connection of scr without gate terminal
TRIAC is 4 layer or 5 layer device
Hi sir. Is the diac and triac turn off method is the same as SCR?
Nope, diac and triac is bidirectional device, so we can turn it off only when we reduce current below holding current.
@@EngineeringFunda thank you. Your lectures and informations is big big help
What are the differance in triac
sir i think the symbol of triac u have drawn have mistakes if it so pls correct them
Sir my best suggestion is , cover your mic with socks . So that noise reduces !
Your positive comments motivates me, Thanks and welcome 🙏
@@EngineeringFunda Your welcome sir and my full portion is covered in your channel. Thank you so much.
What is the function of triac
