Introduction Transistor

On the following pages you will learn about and understand transistors and their areas of application. Transistors are extremely flexible and are used in a large variety of circuits. Here, you concentrate on a simple bipolar junction transistor (BJT), which stood at the beginning of all transistors and still plays an important role.

You get to know what a bipolar junction transistor is, who it is connected in a circuit and what properties it has. In the further course you build some basic transistor circuits and realize how transistors are used as amplifiers and electronic switches.

Before you can start with the first experiments, you need to make a few preparations.
