NPN transistors contain negative, positive, and negative layers while PNP transistors contain positive, negative, and positive layers. But the purpose of the transistor (an electrical switch or amplifier) is essentially the same. What is a transistor and its function? A transistor is a semi-...
A lateral PNP transistor with concentric p-doped emitter and collector diffusion zones in an n-doped base layer epitaxially grown on a p-type silicon substrate, covered by a layer of silicon oxide, has emitter and collector electrodes in the form of metallic patches on the oxide layer overlying...
NPN and PNP are two types of transistors. Transistors are semiconductor devices made of doped p-type and n-type junctions. This article mainly introduces the differences between this two kinds of transistors, the methods of distinguishing them, and the application of them. Read ...

You can also make the LED turn ON when it is dark instead of when it is light. To do this, replace the NPN transistor with a PNP transistor like this: Build It Yourself Now it’s time for you to build this circuit. It’s very important to build stuff, not just read about it. ...
The configuration of a common emitter transistor is widely used in most electronic circuit designs. This configuration is evenly appropriate to both the transistors like PNP and NPN transistors but NPN transistors are most frequently used due to the widespread use of these transistors. ...
TransistorThe transistor is a 3-terminal semiconductor device that is either use to amplify a signal (voltage or current) in analogue circuits or acts as an electronic switch in digital circuits. Both bipolar (npn and pnp) and CMOS (nMOS and pMOS) transistors, along with unijunction and JFET...
