The working principle and characteristics of a transistor are essential knowledge that electronic technicians must master. There are three commonly used working states for a transistor: cutoff, amplification, and saturation, each with different conditions and characteristics. In fact, there is a fourth working state of the transistor in the circuit, although this state is not commonly used, it is also something we must understand.
