Basically the power supply is reversed. The NPN can be used for higher frequencies since electrons can move faster than holes.

What is the difference between npn and pnp transistor in the application?
There is no difference they perform the same functions.
What are the two classifications of transistors?
The two basic types of transistors are the NPN transistorand the PNP transistor. Certainly there are many other semiconductor devices, but these are arguably the two basic ones.
Transistors Basic material of?
silicon ang germanium there are two types of transistor \ 1. PNP 2. NPN silicon ang germanium there are two types of transistor \ 1. PNP 2. NPN
2 transistor analogy for scr and derivation for expression of anode current?
a thyristor can be considered as two complementary transistors , one pnp- transistor, and other 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.
What is difference between npn ans pnp transistor?
NPN and PNP transistors function in essentially the same way. The power supply polarities are simply reversed for each type. The only major difference between the two types is that the NPN transistor has a higher frequency response than the PNP-because electron flow is faster than hole flow. Therefore high frequency applications will utilize NPN transistors.
What is the difference between BJT and NPN transister?
Mainly there are two types of transistors. They are BJT (Bipolar Junction Transistors) and FET(Field Effect Transisters). In BJT, there are two types called PNP and NPN. Actually NPN means a BJT transister.
Why are npn transistors used more often than pnp transistors?
The primary reason that NPN transistors are used more often than PNP transistors is that they usually operate faster (at higher frequencies) because the mobility of the current carriers in NPN transistors (electrons) is much higher than that of the current carriers in PNP transistors (holes).
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.
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 PNP transistors be used in place of TIP31 transistors?
No...TIP31 is NPN. The complementary PNP is a TIP32. They are both large high power (40W) devices.
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
Is it emitter-base junction should be reversed for both npn and pnp transistors acts as a amplifiers?
no, the emitter base junction should be foward for both npn and pnp to act as amplifiers.
What is btj transistors?
They are NPN and PNP. BJT mean bipolar junction transistors. there are two P-N junctions in BJT transisters.
