A transistor is defined as a semiconductor device that’s fundamentally built with three terminals for amplifying or switching electronic signals and electrical power purposes. Commonly classified into Bipolar Junction Transistors (BJT), and Field Effect Transistors (FET), these devices allow for the existence of radios, computers, calculators, etc. that you use today.

Well, with modern-day transistors like the BC547, 2n2222, 2n3904, etc. being used in microcontrollers (E.g. Arduino) or electrical circuit building applications, it’s important that we take a deeper look into transistors in today’s blog.
