"P" is for Positive and "N" is for Negative
So basically put a PNP Transistor Would use N to Switch P, in the name "PNP" or "NPN" the first character is for the polarity of the Collector-pin, the second for the Base-Pin, and the third for the Emmiter-pin.
So if you have a PNP Transistor you can`t just replace it with an NPN as the polarities differ. If you can find a way to change those polarities then sure it could work.
The Collector-pin basically receives the bigger current. The Base-pin determines how much of that current will be transferred to the emmiter-pin. So in a PNP the base current could for example be 0V and the Collector 5V, this will allow a free flow of current from Collector to Emmiter, the usage of a transistor in many cases is to switch high current with lower current.
The main difference is that a PNP transistor uses "holes" as carriers and an NPN transistor uses electrons as carriers (It is to be remembered that the flow of current is always in the direction opposite to that of the flow of electrons).
The difference in the symbol for the two transistors are that the PNP transistor will have an arrow pointed to the base from the emitter, and the NPN has it pointing outside.

When a PNP transistor is connected in a circuit it can be used as a power amplifier because?
A PNP transistor has no advantage or disadvantage over an NPN transistor in its ability as an amplifier. Rather, the current-handling capacities of the transistor determine if it's usable as an amplifier.
Why is an ordinary junction transistor is called bipolar transistor?
Because it uses N-type and P-type semiconductor, usually silicon.The construction will either be NPN or PNP, with the different types in a "sandwich" construction.
Why use a npn transistor in a common emitter bjt single stage amplifier circuit?
You can use an npn or a pnp bjt in a common emitter amplifier circuit. The decision of which one to use is based on whether you want the collector and base to be more positive (npn) or more negative (pnp) than the emitter.
How do you identify a pnp or npn transistor?
If you know the base of the transistor, and you have an ohmmeter that puts out more than about 0.7 volts, you can check base to emitter or base to collector as if it were a diode, and it will conduct when the more positive lead of the ohmmeter is connected to the P junction. That will tell you if the transistor is NPN or PNP. If you don't know the base, you can check all six directions. Only two should conduct, the two that are forward biased towards the base.
How many pn junction transistor contain?
two jun. b/w three layer of either pnp or npn
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.
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.
What is the major difference an NPN transistor and a PNP transistor?
The NPN transistor has its conduction curve where the base is more positive than the emitter, while the collector is also more positive than the emitter. The PNP transistor is exactly opposite, with its conduction curve where the base is less positive than the emitter, while the collector is also less positive than the emitter.
What is the difference between npn and pnp transistor in the application?
There is no difference they perform the same functions.
How many pn junction does transistor contain?
Two, either in NPN or PNP transistors
