TRANSISTOR OPERATION

Today, I explain a little how a transistor works.

Mosfet or as we all know, switch; it is an electrically operated switch that allows a current flow, it is made of silicon.
These devices can act as a switch without moving parts, and their main function is amplification.
Doping is used to improve the conductivity of semiconductors.

HERE ARE SOME PICTURES THAT EXPLAIN A LITTLE BIT:

 










This are  two links of two videos that explains better the functions of a TRANSISTOR:
