How to Identify PNP or NPN Transistor

[@striela1]

thank you so much, my friend! Clear and simple! Greetings from Italy!

[@colindiggle9377]

thanks so much tech wish all vdeos was like this pure and simple helped so much lol xxx

Welcome

[@dredre1official25]

This video teach me something . N= negative and P= positive and to know if it npn or pnp just know that p positive in red and n negative is black that's it

[@davidklbecek827]

So clearly explained, thank you

[@33798]

Indeed you explained in a simple manner

[@TechStudyCell]

Thanks

[@t.nitheesh5898]

I had to do a project on transister this help me a lot . Thank you bro.

[@TechStudyCell]

Glad it helped

Very clear explanation 👌 good job brother thank you so much 🙏❤.

[@Theodor1st]

Hi! What if I get a reading with only one of the other two terminals? Does this mean that the transistor is broken? (tested transistor: A2149) Thank you.

[@akramaraien8702]

It was helpful for me, thank you

[@TechStudyCell]

Glad it helped!

Nice video shot, thank you for sharing it, keep it up :)

[@kakejagadesh1068]

very superb explanation

Thanks brother

[@mmartinez3619]

good method. Well done! Thank you

[@shahnawazrangrezz3086]

Very good method..

Thanks

[@priyotoshdas5576]

sir how to measure resistance.this video is very nice i am supporting you.

[@TechStudyCell]

+priyotosh das Thank you for your feedback. Keep supporting us.
To measure resistance you may refer the following video.

V informative vedio thank you brother.... ✌️

[@TechStudyCell]

Always welcome

[@naderhumood]

Cool test method brother..but .what is the unit for reading.... .? If y don't mind

[@grilledchickenwrap]

what if the PNP transistor one has reading of 362 and the other one is O.L what does that mean ?

[@donsahgodfred9941]

Thanks man

[@UzunKamis]

Thank you I was looking for this.
1. How can I determine if it is npn or pnp by looking at the datasheet?
2. Some schematics write *Gate* , *Source* and *Drain* . In this case, do *Emitter* and *Collector* mean *Source* and * Drain*, respecitively?

[@Dpk_YT]

gate source drain is mosfet transistor ...simple transistor are npn and pnp

[@jyothikini3825]

Thank you 😊

[@YoshimoPlayGames]

How to know if it is PNP or NPN, well... Before you use them in a circuit and connect to something I would strongly reccomend you take a look in ANY DATASHEET connected to number on the cover of your transistor

[@kanchankondhare]

Thanku sir very nice......

[@geniusnocopyrightmusic9368]

I have a transistor when I connect negative lead to left and positive lead to middle and right I get reading then what type of transistor it is?

[@airw_orthy]

NPN Transistor

Thanx

Sir. Thanks is this way testing all transistors. Like bd139

good sir

[@davidnathaniel789]

Awesome!

[@TechStudyCell]

Thanks

[@AudiA8A6A7]

and if they are burned :)?

[@jayeshnair877]

If you are using analogue multimeter this will be wrong. In analogue multimeter you have to test with black negative probe on the base of npn transistor and opposite in pnp.

[@ashwaniwani9864]

Sir I satisfies

[@pg7703]

why we will not reading in reverse condition...???

[@SHANUSHAH]

Because it's a diode back to back and diode will only conduct one way

[@ashwaniwani9864]

Sir aise practically video whole instruments ka dijiye

[@MahadevBadwadgi]

Dono side me reading show kar raha hai kaise check kare

[@MahadevBadwadgi]

Kit me laga huva hai isiliye Aisa dikha raha hai kya sir

[@ملكةزماني-ذ4ر]

Differentiate between NPN and PNP transistors. According to you which one is going to switch faster.
؟؟؟؟

[@tamrimohamed7748]

i find my transistor burned it give nothing how ican know his type

[@TechStudyCell]

If you can able to see the part number of the transistor then you identify the type PNP or NPN

[@tamrimohamed7748]

@@TechStudyCell the number i see is A 684 y922

[@avinashpawase2442]

but how to chek it is good or bad

[@TechStudyCell]

+Avinash Pawase
You can check with a simple transistor tester circuit.

[@manojdas6936]

This video create confusion, please explain in more detail

[@johnbenchardgomez2103]

When connecting a transistor in a circuit, why must the technician know whether a
transistor is NPN or PNP?

[@burgerman5335]

negative charge passes through the emitter, and a positive charge out the collector.(talking about PnP) when an amount of charge is passed through the base, or middle prong it allows energy to pass through. picture the scenario, A battery is powering a low voltage lightbulb, but energy flow passes through the tranistor.(collector to emitter) a copper wire is attached to the middle prong or base, when I touch it, energy passes through and the lightbulb lights up. I believe nPn is of the opposite nature. But I'm still learning how transistors work and I know this doesnt answer your question. I'm not an electrition and most likely got the entire idea wrong. But I hope this helps. : )
