How to Identify PNP or NPN Transistor

This video explains, how to Identify PNP or NPN Transistor with the digital multimeter.
Here I have use two BJT transistors (BC547 &BC157) to check the type (PNP or NPN)
Transistors are very important as almost every electronics circuits use transistors for several purposes (as a switch, amplifier etc).

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

[colindiggle]

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

[dfiglide]

excellent, clearly explained, helped me a lot, thanks for posting

[andrewmiller]

Well explained and easy to understand. Thank you.

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

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

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

Indeed you explained in a simple manner

[panneerselvam]

Thank you for your very clear explanation.

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.

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

[naderhumood]

V informative vedio thank you brother.... ✌️

[priyotoshdas]

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

[grilledchickenwrap]

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

[geniusnocopyrightmusic]

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?

[naderhumood]

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

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?

Lol that random creature walking in view.

[milvolts]

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

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
