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).
How many pn junction does transistor contain?
Two, either in NPN or PNP transistors
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.
Why is NPN transistor a straight switch and Why is PNP transistor an inverted switch?
npn and pnp transistors have the same operation as one another, they are both switches, pnps may be known as inverted switches because they work on negative voltage supplys and not positive voltage supplies.
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 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).
Which transistoris widely used?
Npn transistors are widely used
What is btj transistors?
They are NPN and PNP. BJT mean bipolar junction transistors. there are two P-N junctions in BJT transisters.
How many pn junction does transistor contain?
Two, either in NPN or PNP 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 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 difference between npn ans pnp transistor?

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.

Why is NPN transistor a straight switch and Why is PNP transistor an inverted switch?

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.
Why you use majority NPN transistor but not PNP transistor?
please send the answer...................... answer: people are positive animals we think positive +5v for instance is the predominate voltage in a computer PNP will work fine on a -5v environment but +5 volt is here to stay so NPN transistors are predominate
