Npn vs pnp

Why is NPN transistor prefered over PNP? When using transistors in electronic circuits for switching purposes, an NPN transistor is preferable to a PNP transistor because the switching speed of an NPN transistor is greater than that of a PNP transistor.

What is the meaning of NPN and PNP?

Both NPN and PNP are bipolar transistors. These are current control devices mainly used to switch and amplify signals. Usually the circuit uses an NPN transistor because the drive current in an NPN transistor is mainly electrons and the drive current in a PNP transistor is due to holes.

How does a PNP transistor work?

PNP transistor. The PNP transistor receives a positive voltage at the emitter junction. A positive voltage across the emitter causes current to flow from the emitter to the collector, while a negative current flows to the base (current flows from the base to the ground).
