- Do you have a NPN transistor and you are not sure how to test it? I will show you a simple way on how to test your NPN transistor with a multimeter. After you follow how to test a NPN transistor, you will know if you have a good or bad NPN transistor. You will also know how different NPN transistors packages look like. You will also know how a transistor work.
A most excellent presentation. Very clear and beautifully presented.
I can now test transistors with confidence after watching your informative video, thank you.
Bravo from France. So clear, good explanation and practice👍
EXCELLENT and simple explanation - Thanks
Most helpful video I could find
Awesome Video Thank-you for your time and effort
Brilliant video thanks bud
Definitely helped me review. Thanks!
That's great! Please make videos with others components of electronics.
Thank you so much for your helpful job, just keep it up.
It's very helpful 👍
Thanks
Best demonstration appreciate thanks 🙏💐👌👍
Thanks. Helped me verify the 2SC2555 from my PP-7B power supply is good.
Well Mate Ihave To say its Great.Its better Then in The Collage 60 Min Only To explain. And Here 4:36 And You a Pro.Thanks Alot Its Greatful
Grait video😍
Thanks😊
Creative video,thanks :)
thanks , very nice video
FINALLY UNDERSTOOD!
great video! thanks a lot
Glad you liked it!
Muito bom trabalho , grato
thanks, super. very very goood teaching............ from india
Thanks and welcome
3/10 Needs more hand animation
Ssuuppeerrbbb Thanku
Hi, is this method for the transistor on the board connected to the battery or desoldered? Regards
So, collector and emitter are giving me lecture (both positions), and I have a question, is it common that these type of of transistors manage the signal of 12 volts that activates the relay in order to make a motor work? By the way I already tested the relay and it is ok, but no 12v signal, suspicious #1 NPN transistor!
OL is for open line
thank you,,,very good explanation,,
Kindly post video for PNP transistor also
When testing an unknown BJT, the base pin (of both NPN and PNP) is easy enough to determine; but how do we distinguish which pin is the collector and which is the emitter?..
Usually, just use the part number to search up the datasheet.
If it doesn't have a part number you really can't even know if it's a transistor or something else (as the same kind of packages are used between a variety of components)
one voltage drop should be slightly different from the other (google search).

Isn't it the current through the base of a BJT that matters, whereas MOSFETS its voltage?
Awesome excellent thanks beautiful way
Sir can I ask what kind of smd Transistor with yhe marking of
Marking of NB AB
Get an M tester they cost about $7 to $10. It can test transistors and lots of other things.
WHY the 0.3V to 0.7V? Why these two min and max readings?
make it so, you can read the multimeter to see what the diode setting is...for those that are not multi meter savy. please
isn't one test is missing - Black Led on Base and Red on Collector and Multimeter should give you an "OL" Over limit reading
Wow
Very Informative Thank You -- This video was a bit slow, so i set playback at 2X Speed -- much better!
Worst backround sound
Writing/typing out each letter at a time is time wasting and annoying. Just print the line and get on with it!
Agreed. After watching for 15 seconds, I had to exit the video
For some us morons like me, the rubbing out gives us time to absorb and try to put things into long term memory.
What is with the fake drawing? It's off-putting. Are you "Thing" from the Addams Family?
Don't forget to mute your tv
Painting makes it painful to watch. Waste of time.
you know why nobody does the hand drawing animations like this? Because it is annoying...original, but not useful in a tutorial really
Worse tutorial ever.
For some of us, this pedestrian approach is exactly what we need. And of course, you didn't need to watch it.
