There are two basic types of bipolar transistors. One being the NPN and the other, the PNP. In your situation, you're dealing with a PNP transistor, that requires a negative going voltage on the base connection to make it function. Without going into all the details, there are several ways in which this transistor can be utilized.
The low frequency refers to the frequency range in which a transistor will function. The low frequencies could be for audio, power regulation or several other applications where dealing with signals in the higher frequency ranges aren't necessary, such as radio frequencies.

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).
Advantages of npn over pnp transistors?
because of high output drive,easy to manufacture and takes less space and also low power consumption...
How many pn junction does transistor contain?
Two, either in NPN or PNP transistors
What is a transistor that is normally on with no applied signal?
The PNP transistors conducts when there is no signal at base (0V or grounded), when base current is increased the conduction of PNP transistor decreases.
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.
What is btj transistors?
They are NPN and PNP. BJT mean bipolar junction transistors. there are two P-N junctions in BJT transisters.
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).
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.
PnP is the acronym for what term?
Positive-Negative-Positive (in transistors).
Advantages of npn over pnp transistors?
because of high output drive,easy to manufacture and takes less space and also low power consumption...
How many pn junction does transistor contain?
Two, either in NPN or PNP transistors
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 a transistor that is normally on with no applied signal?
The PNP transistors conducts when there is no signal at base (0V or grounded), when base current is increased the conduction of PNP transistor decreases.
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 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.
Where can one purchase a PNP transistor?
One may purchase a PNP transistor from a local electronics hobby shop or a chain such as Radio Shack. The website "Mouser" also has transistors and downloadable data sheets for them.
