Transistor ( Transfer of Resistor )

Transistor ( Transfer of Resistor )

Transistor is a solid state device. It is used in current, voltage or power control device. It is made by the germanium or silicon. It is commonly knows as the bipolar junction transistor.
There are two types of the Transistor:

1) PNP Transistor
2) NPN Transistor

1) PNP Transistor:- N type material sandwiched between two layer of P type material is knows as the PNP Transistor.
PNP Transistor
PNP Transistor

2) NPN Transistor:- P type material is sandwiched between two of the N type material is knows as the NPN Transistor.

NPN Transistor
NPN Transistor
Transistor in the present of the three region

1) Emitter

1) Emitter:- The first region of the Transistor. The main function of  supply the majority charge to the base and very highly doped compared to base and collector region (to other region).

2) Base:- The second region of the Transistor. The Base is very lightly doped comparison to other region. The base layer is very thin layer compared to other region.

3) Collector:- The third region of the Transistor. The main function the collect of the majority charge through the base that is called Collector.
