I'm now totally confused about transistors now. How is it the internal of the transistor is just two diodes that seem to be in parallel with one end, but other transistor videos talk about the 3 terminals as having a base, emitter, and collector? They also explain how they can be used to amplify a signal by being a lower power switch to allow a larger power flow on the other connections?
Thank you for the video. I have a washing machine and dryer with no power. Do I have to take all these parts off the PCB board to test? Do you have any PCB video's?
Nice.you are very honest and true.some guys do fake video but i like the way you explain the truth in short.i have subscribe.i will doenload every video you make.thank you
A small advise for you when checking a resistance that time don't tuch tha both hands resistance leads why because our body resistance also add (not only resistance some other components also)
Ive been trying to find someone to explain that exact reason to me. Would you be willing to explain why you want in diode mode. Wasnt sure because of the bias voltage or what been very eager to learn. Thanks in advance
This one is really good among the rest sir, i watched different videos regarding this testing and checking component but hard to understand, but luckily i found one (your video) with the same digital multimeter as mine. So now i understand things. Thank you. I subscribed to your channel. Hope i could learn more. Specially testing component for the gadgets, celphone laptop electric components. Thank you.
Hi ibuy some electronics like video player dvd player video cameras used one I just need some information can you test with probe multimeter on that can you give me some ideas or information please many thanks
Not certain about the points made but ,if anyone else wants to uncover how to make electronic circuit boards try Sovallo Circuits Expert Fixer (just google it ) ? Ive heard some unbelievable things about it and my cousin got great results with it.
You are teaching how to test components but without the DMM switchings. Show us also the DMM what to switch to for a particular component. Anyway nice video
Cheers for the video content! Sorry for chiming in, I am interested in your thoughts. Have you tried - Tarbbatigan clean errors Tip (just google it)? It is a good exclusive guide for discovering how to fix electronic devices minus the hard work. Ive heard some amazing things about it and my BF at last got amazing results with it.
My issue is a little off topic we build custom motorcycles and the bigger the motor the motor starin that is put on the batteries even if high CCAs. So what we are thinking about doing is adding a capacitor to give the battery a boost during starting. I have been watch all sorts of youtube videos on this and people are using anyware from 14v-50v capacitors. From my understanding is the voltage doesn't matter since that is just a maximum voltage the unit can handle and with heat and age that maximum voltage rating can drop causing the capacitor to burn out. So we are planning to use a capacitor at least 3x the bikes voltage which is about 13.8. But what we are most concerned about is the farad rating. I watch an HVAC companies video on capacitors and they say that too large of one can burn out their motors so they deal with microfarads instead. So we are wondering if this will be an issue with a motorcycle starter and other electronics that there is a certain farad rating we should stay below or not? I have see all sorts of capacitors for cars that ranged from 1 to 50 farads and more. I don't think we need anything that massive but we want something to give a good boost to the battery at start up so the bikes fire easier instead of lagging on the compression stroke with all the lights fading looking like the battery might not have enough oomf. Can you advise a capacitor rating and if they should include a diode, resistor, or voltage regulator? Since they will need to be small enough to hide on a motorcycle we will most likely just have to order basic capacitors from overseas and what not to wire ourselves compared to one of the large stereo units that comes complete ready to bolt in and connect the wires. Any help would be appreciated. Thanks,

Hello. My job is to repair electronic boards in Iran and recently I faced a strange problem. As I was repairing a BMW 730i 2017 wing mirror electronic board, there was a dubitable component from ST electronics company which I couldn't find its datasheet on the internet. That was a 2 pin component with Zb2b part number. I am wondering if you could help me with finding out what component I should replace with this. sincerely.
These tests are not all the way a "valid" ones. It can be shown good on a tester, but not good when "on duty", which means the component must be connected to a powered circuit and then the final word: good or bad.
We know that to test a component you have to use a voltmeter with rodes from both sides! Which you have been doing. The trick is to how to use the voltmeter....what did you set up the voltmeter on?
Probably this was addresed, but NEVER DISCHARGE A BIG ELECTROLYTHIC CAPACITOR WITH YOU FINGER! (You could end up dead, burned or shocked) Discharge it with a proper lead with a resistor to a chasis or grab a screwdriver from the insulated end and shortcut the terminals. In the last case spect a spark.
if the continuity buzzer beeps in a resistor while in a circuit board but does give a ohm readings is that resistor sorted and bad?? also if the readings of transistor is showing 1 on both side but does not beep is that bad too?
While in a circuit board there would many resistors those are connected in series that's shows readings in ohms while individually buzzer beeps because of low resistance. if the readings of transistor is showing 1 on both side but does not beep. In this situation select diode mode in meter and then try it sometime the range is higher then the selected mode in meter so,it shows 1 or OL.
While testing resistance, our body contact(fingers holding ends of resistance) shown is not correct!! There will be substantial error while measuring high value resistance. One should avoid such contact.
Electrical & Electronics Projects. ..i noticed 3 resistors that are next to ea other are green color not sure if their bad,how can i order them from amazon? Do i get the same color coded ones?

that is the best and the easiest tuto i can watch, good job bro
thank so much for take me to another level of my life through your lesson, am self employed now this according your video in youtube
A small advise for you when checking a resistance that time don't tuch tha both hands resistance leads why because our body resistance also add (not only resistance some other components also)
venkatesh dukkupati ...I appreciate your knowledge sir, please i really need a consultant, can you send me your phone contact?
VERY GOOD INFORMATION ABOUT CHECKING ELECTRONICS COMPONENTS BIG THANKS
Good tutorial. My only add would be when testing semiconductors, the meter should be switched into diode test mode.
Ive been trying to find someone to explain that exact reason to me. Would you be willing to explain why you want in diode mode. Wasnt sure because of the bias voltage or what been very eager to learn. Thanks in advance
Thank you. Can u please zoom in on which settings u used on the multimeter next time, please?
And don't put your and in the way of the readings on the multimeter !
Out standing videos 👍👍👍 buddy good to know 🤠 thanks for the update.
You're amazing man...One point very important...End to end diodes is Transistor but PN Junction is diode

can you create vdeo on how to check components which are part of circuit board?
Hello. My job is to repair electronic boards in Iran and recently I faced a strange problem.
As I was repairing a BMW 730i 2017 wing mirror electronic board, there was a dubitable component from ST electronics company which I couldn't find its datasheet on the internet. That was a 2 pin component with Zb2b part number. I am wondering if you could help me with finding out what component I should replace with this. sincerely.
I can't. If the pcb is simple, you can reverse engineer it and draw its circuit. You can deduce an equivalent of the component
Clear and to the point explanation 👍🏻
Thank you very much for this great information I have to look it up every time because I got a bad memory LOL
Welcome!
Explained in the simplest way. Thanks a lot
Thumbs up easy but informative. If this my professor i will not drop my subject
Good video, very useful. Please provide videos, How to test the same component after soldered in the PCB with power supply and without power supply.
I am from Sri Lanka your session is very good
Wonderful lecture.But I have a question ,when testing the fuse if both of the ends were touched by fingers could the test result correct?
the best video to check the componets to you tube ever bravo.
can you make video about testing capacitor inside circuit?
Hello. Are there devices that can check all components without soldering for example on the motherboard?
Finally I can understand, thank you for the lecture
Very nice Dear sir I like your spake n selitio....
I got the green capisitor on treadmill and it shows numbers on multimeter is it good or bad because the others are not showing any numbers. thanks
thanks for the interesting video, greetings from Croatia !!
Pause 7:58 ( Blue line and symbol - - ) it is mean negative terminal.
These tests are not all the way a "valid" ones. It can be shown good on a tester, but not good when "on duty", which means the component must be connected to a powered circuit and then the final word: good or bad.
7:37
Me when I don't want to make a video but have to
FANTASTIC AND EASY TO UNDERSTAND
Am still figuring out electronics it helped me alot
Wow an infomative english video. Thanks for sharing
Thanks for visiting.
We know that to test a component you have to use a voltmeter with rodes from both sides! Which you have been doing. The trick is to how to use the voltmeter....what did you set up the voltmeter on?
Thank you so much 👨 man you have just done great job I am so happy now we need more of this common sense
So much more gain a lot.
Thanks for these
It's not always when a tranformer has continuity that it's ok, a shot transformer can also beep
Probably this was addresed, but NEVER DISCHARGE A BIG ELECTROLYTHIC CAPACITOR WITH YOU FINGER! (You could end up dead, burned or shocked)
Discharge it with a proper lead with a resistor to a chasis or grab a screwdriver from the insulated end and shortcut the terminals. In the last case spect a spark.
Thank you for you video! Can you do one for different relays?
Exilent performance 👍👍
A very good demonstration for learners
In emergency light they used (yellow voilet black gold black) now it damage which resistor can i use.
Thank u
Thank you very much for your precised method of testing
Very understanding, i love ur channel 👍

very good and well explain,thank you.
Pls I like your video pls make a video on how to repair multimeter if given faulty reading
Best videos ever I like it make me to understand components but I ve a question for you
Nice. Thank You 🙂
I have a g.e microwave that heats up but the display doesnt come on would it be a resister,transistor or capacitor that might be the issue?
If the display doesn't come on may be a fuse is burned if there is.The fuse could also be in a resistor form with low resistance.
Electrical & Electronics Projects. ..i noticed 3 resistors that are next to ea other are green color not sure if their bad,how can i order them from amazon? Do i get the same color coded ones?
Coils and transformers could be shorted "inside" because od overheating or mechanical shock.
Nice video for knowing the testing of electronic components
Thank you so much!
Great work nice teaching
Thanks and welcome
Thank really good lesson guy

I was expecting you to explain the settings on the meter like voltage and amh
Same here.
Thanks for your vid love it
Thanks for updating such type of vedio
Excellent video, thank you.
Wonderful video
Very clear class
Glad you liked it.
Very educative
Good values for diodes are between 0.3 to 0.7
very nice explain thank you so much
Great demo. Thanks.
You are welcome!
Very nice demonstration of teaching electronic equipment I really appreciate ur effort.
nice video but never mix transistors with back to back rectifier diodes, they are not the same.
I t would be helpful if you could describe the function of the e-device as you test it? but still useful for testing the parts?
Thanks bro. Kal pass hojayunga mai.
Its very funny way of Testing inductors you show us lol...i thought you were testing how much Henry...or MH, uH....the inductors are....but you are so funny.
so nice
Your the man pre..
Is it is correct method of cap:testing ?
