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!

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

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.

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

@YoshimoPlayGames 4 года назад

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

@UzunKamis Год назад

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 9 месяцев назад

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

@airw_orthy 2 года назад

NPN Transistor

@pg7703 6 лет назад

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

@SHANUSHAH 6 лет назад

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

@AudiA8A6A7 4 месяца назад

and if they are burned :)?

@jayeshnair877 2 года назад

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.

@user-vj5wd6wq1v 4 года назад

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

@avinashpawase2442 7 лет назад

but how to chek it is good or bad

@TechStudyCell 7 лет назад

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

@tamrimohamed7748 5 лет назад

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

@TechStudyCell 5 лет назад

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

@tamrimohamed7748 5 лет назад

@johnbenchardgomez2103 3 года назад

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

@burgerman5335 3 года назад

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. : )
