Meaning of NPN and PNP?
pnp answer
What are the functions and empowerment of PNP as per PNP laws?
pnp and npn transistor
कैसे NPN ट्रांजिस्टर PNP ट्रांजिस्टर से अलग है?
diff. between npn and pnp transristor
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.
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.
Field-effect transistor NPN or PNP?
NPN, PNP only classified to BJT, while FET classified as P-channel , N-channel
Why to use pnp transistor in fire alarm circuit?
You can use a PNP or an NPN transistor in a fire alarm circuit. Both will work. It all depends on how you want to energize the alarm, and with what polarity of signal.
What kind of semiconductor is produced by adding indium in semiconductor crystals pnp or npn?
pnp
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 be replace npn transistor series regulator with pnp?
no
Is PNP sourcing or sinking?
PNP is sourcing. NPN is sinking. You generally connect NPN to ground and your PLC(or any load)input. With PNP you connect to V+ and to your PLC. Your PLC (load) should have the same ground or V+. Sourcing (PNP) provides a path to +24DC generally. Sinking (NPN) provides a path to 0V DC.
Why PNP and NPN are used in direct coupling?
To save a decoupling capacitor & biasing resistors for the PNP.
