Very clear explanation
I saw 30 videos about check bjt
But this one stand in my mind
Bro, உங்கள் வீடியோ மிகவும் பயனுள்ளதாக உள்ளது நன்றி நண்பா.
I'm new Subscribers your video very useful.
Thanks.
BJT Explanation good... For choosing/Selecting BJT wt are all important parameters we need to check in datasheet.. Please reply me ASAP
+MANIKANDAN RAJENDRAN
Forward voltage drop( Rce)
maximum switching frequency
Beta value
Slew rate (if it is given in datasheet)
It will be useful if you test with fault BJT too
நண்றி சகோதரா
Sir Common base common collector common emitter configuration pathi explain pannunga plz

Thanks. How to find the collector and emitter pin are PNP and NPN transistor?

LM431 zener diode எப்படி Check பண்றது.....
Can't check zener with multimeter.
@@ElectronicsForUs Then how to check it....
We have to check with it's voltage across it when it is connected in circuit
@@ElectronicsForUs Can you explain with detail????
Three pin zener diode.....
Positive Input voltage ah zenerல் anode ல Connect பண்ணனுமா இல்லை Cathode ல Connect பண்ணனுமா.....

Ok. I ll put a video.
BJT transister வச்சி amblifier செய்யமுடியுமா
Yes
Collector ஐ Multimeter +ve விலும் Emitter ஐ -ve விலும் Continuity mode la check பண்ணா எதாவது Resistance value வருமா வராதா??????
It will be infinity. If you give supply at base then you will see some value.
@@ElectronicsForUs Infinity but mosquito circuit transistor show some impedance value between Emitter and collector.....so its the transistor is kk or not.....
In your video mentioned about the how to check the transistor i understood its so well......if we buy new transistor and check Emitter and collector with continuity mode in multimeter....it shows some values (impedence) or not.....
Because my transistor shows some value between Emitter and collector.....i am so confused...
You cannot measure resistance when transistor connected in circuit.
@@ElectronicsForUs kk i am asking about new transistor without any circuit.....
Use multimeter to check Emitter and Collector with continuity mode what will happen.....???? Either it will show any impedence value or not??????
மேலும் அப்படி Value வந்தால் அந்த Transistor ஐ உபயோகப்படுத்தலாமா??????
மேலும் ஒரு Transistor ஐ Circuit ல இருக்கும் போது அதனுடைய Condition நன்றாக இருக்கா இல்லை Spoil ஆகிவிட்டதா என்பதை எப்படி கண்டுபிடிப்பது.????
