Transistors are one of the most important electronic parts in the world. They changed the world as we have known it and set the basis for the information age. To get a better understanding how these little things work, this video series wants to answer a few questions about them. 

In the first part we want to show a few characteristics of the bipolar transistor (BJT), the first transistor put in operation in 1947. We will discuss its internal structure, the difference between an NPN and PNP transistor, the different characteristics and the regions of operation.
