In a npn transistor the current carriers are

WebApr 10, 2024 · The transistor is a three-terminal current control device, that can be used to create complex electronic circuits. Even though there are other types of transistors, Bipolar Junction Transistors (BJT) are still popular and used everywhere. So, we will discuss about BJTs and then difference between NPN and PNP transistors. WebThe main difference between the two types of transistors is that holes are the more important carriers for PNP transistors, whereas electrons are the important carriers for NPN transistors. Then, PNP transistors use a small base current and a negative base voltage to control a much larger emitter-collector current.
