What is a Transistor? How Transistors Work? (BJT Transistor Tutorial)

Hello friends! In this lesson, I will try to explain you the transistor's working principle without touching upon the structure and types of the transistor. A transistor is a circuit element that acts as an amplifying or switching in a circuit. It consists of joining three semiconductors of type-P and type-N. Here I will describe the Bipolar Junction Transistor.
