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!
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)
A most excellent presentation. Very clear and beautifully presented.
I can now test transistors with confidence after watching your informative video, thank you.
Thankyou simple and straight to the point
This will help me figure out my ecu for my car. Thanks!!! Im a go thru all your video's.
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
Bravo from France. So clear, good explanation and practice👍
EXCELLENT and simple explanation - Thanks
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
Awesome Video Thank-you for your time and effort
Brilliant video thanks bud
FINALLY UNDERSTOOD!
Thank you very much from informations khalid from Morocco Casablanca
Thanks. Helped me verify the 2SC2555 from my PP-7B power supply is good.
Definitely helped me review. Thanks!
Best demonstration appreciate thanks 🙏💐👌👍
Most helpful video I could find
thanks, super. very very goood teaching............ from india
Thanks and welcome
Does this test method apply to transistors installed on the PCB?
yes, but you also have to take into consideration of circuits that are in parallel to the transistor which can lead to misreading.
Hi, is this method for the transistor on the board connected to the battery or desoldered? Regards

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?
The current through the base matters after you establish that the npn is working OK.
3/10 Needs more hand animation
great video! thanks a lot
Glad you liked it!
Creative video,thanks :)
Kindly post video for PNP transistor also
OL is for open line
thank you,,,very good explanation,,
Muito bom trabalho , grato
isn't one test is missing - Black Led on Base and Red on Collector and Multimeter should give you an "OL" Over limit reading
Very Informative Thank You -- This video was a bit slow, so i set playback at 2X Speed -- much better!
Get an M tester they cost about $7 to $10. It can test transistors and lots of other things.
make it so, you can read the multimeter to see what the diode setting is...for those that are not multi meter savy. please
Awesome excellent thanks beautiful way
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.

Wow
Painting makes it painful to watch. Waste of time.
Worst backround sound
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.
you know why nobody does the hand drawing animations like this? Because it is annoying...original, but not useful in a tutorial really
Sir can I ask what kind of smd Transistor with yhe marking of
