Transistor operation

Hey! How are you!? I hope you are well. Today I will show you how a transient works:

The transistor consists of three parts artificially doped (contaminated with specific materials in specific quantities) that form two bipolar junctions: the emitter that emits carriers, the collector that receives or collects them, and the third, which is sandwiched between the first two, modulates the passage of said carriers (base). 

Unlike valves, the transistor is a current-controlled device from which amplified current is obtained. In circuit design, transistors are considered an active element, unlike resistors, capacitors, and inductors that are passive elements.

Thats all for today. This time it was theory, I hope you liked and interested. See you at the next post!

Here are some videos that I hope will make it clearer:
