Transistor
Please refer in our earlier blogs
A voltage or
current applied to one pair of the transistor's terminals changes the
current flowing through another pair of terminals. Because the
controlled (output) power can be much more than the controlling (input) power,
the transistor provides amplification of a signal. Some transistors are
packaged individually but many more are found embedded in integrated circuits.
The transistor is the fundamental building block of modern electronic devices, and its presence is ubiquitous in modern electronic systems.

Type of Transistors
Based upon the application any transistor can be used.
There are two types of standard
transistors, NPN and
PNP, with different circuit symbols. The
letters refer to the layers of semiconductor material
used to make the transistor. Most transistors used today are NPN because
this is the easiest type to make from silicon. This page is mostly
about NPN transistors and if you are new to electronics it is best to
start by learning how to use these first. The leads are labeled base
(B), collector (C) and emitter (E).
