3. Transistor:
Transistor is an electronic device made of three
layers of semiconductor material that can act
as an insulator and a conductor also.
It also known as Bipolar Junction Transistor.

4. Types of Bipolar Junction Transistor
1. n-p-n Transistor: n-p-n transistor is composed of
two n-type semiconductors separated by a thin
section of p-type semiconductor.
2.p-n-p Transistor: p-n-p transistor is composed of
two p-type semiconductors separated by a thin
section of n-type semiconductor.

9. Some Short Notes About Transistor:
Transistor was successfully demonstrated in 1947 at
Bell Laboratories.
Current Conducting within p-n-p Transistor is by
holes.
Emitter current is the sum of base and collector
current.
Ideally Alpha=1 but in reality Alpha is between 0.9
to 0.998
Most commonly used as a switch.454647
