We break down the essential component of modern electronics—the transistor. Transistors are the building blocks behind most of today’s electronic devices, and understanding how they work is ...

Transistors work by using a small amount of electrical current to control a larger current. ... In an NPN transistor, there's a layer of p-type semiconductor material sandwiched between two layers of ...

Let’s take a closer look at how NPN and PNP transistors work. There are two main types of transistor: bipolar junction transistors (BJTs) and field effect transistors (FETs).

How Transistors Work. By Team Digit ... NPN is usually chosen for explanation. The three blocks that make up a transistor are the Emitter, the Base, and the Collector.

Imagine for a moment a simple transistor circuit involving a single NPN transistor with its emitter grounded, ... for accessibility. Think of it as the teenage version of how transistors work.
