Using an ohmmeter on its lowest scale, the base-emitter junction of a transistor
looks like a diode. If it conducts with the base positive, the transistor is an NPN.
If it conducts with the emitter positive, the transistor is a PNP.
(Of course, you need to know which probe of your ohmmeter is the positive one.
DON'T assume anything. Some meters swing one way, some the other way. The
only way to know for sure is to check it with another meter, used as a voltmeter.)

What are the functions and empowerment of PNP as per PNP laws?
pnp and npn transistor
Is BT169 a npn or pnp transistor?
BT169 is neither an NPN nor a PNP transistor. BT169 is a thyristor, otherwise known as a silicon controlled rectifier.
Can be replace npn transistor series regulator with pnp?
no
How do you know if a transistor is a PNP or an NPN?
To know if a transistor is PNP or an NPN,the following should be verified:For a PNP transistor, the base-collector junction is forward biased while the base-emitter junction is reversed biased.For an NPN transistor, the base-emitter junction is forward biased while the base -collector junction is reversed biased.
Difference between NPN and PNP?
NPN and PNP are transistor types. The difference in the way the layers of semiconductor material are doped with impurities.
How do you convert npn signal to pnp signal?
To convert an NPN signal to a PNP signal, you can use an inverter circuit, typically implemented with a transistor or a logic gate. For a simple transistor-based solution, connect the NPN transistor's collector to the power supply, its emitter to the load, and the base to the NPN signal through a resistor. When the NPN is on (high signal), it will turn off the PNP transistor, resulting in a low output, and vice versa, effectively inverting the signal.
Field-effect transistor NPN or PNP?
NPN, PNP only classified to BJT, while FET classified as P-channel , N-channel

Is the pnp transistor in common collector can be replaced with npn transistor?
No. The PNP and NPN transistors are exactly opposite each other in polarity. You cannot just replace one for the other without redesigning the circuit.
Why you use NPN transistors rather than PNP?
Switching is faster in NPN transistor than PNP. Because movement of electrons is faster than holes.
Can an PNP transistor be converted to NPN?
No. The NPN transistor is a semiconductor crystal that was "doped" with n-type dopant, then p-type dopant, and then n-type dopant during manufacture. Just the opposite is true for the PNP transistor. Once it's made, it can't be "unmade" to change it.
What is the difference between npn and pnp transistor in the application?
There is no difference they perform the same functions.
