What is NPN Transistor?
An NPN transistor is a type of bipolar junction transistor (BJT). It consists of a layer of p-type semiconductor material sandwiched between two layers of n-type semiconductor material. The two n-type layers act as the emitter and collector, and the p-type layer acts as the base. The transistor is called NPN because the majority of carriers in the emitter and collector regions are electrons, which are negatively charged.
Difference Between NPN And PNP Transistor With Interesting Facts
Transistors are one of the most important electronic components used in a wide range of applications. NPN and PNP transistors are two common types of bipolar junction transistors (BJTs) used in electronic circuits. These transistors are used as switches and amplifiers, and understanding the difference between them is important for anyone interested in electronics.
