Emmitterstrømmen
Emmitterstrømmen, often translated as emitter current, is a fundamental concept in transistor electronics, particularly in bipolar junction transistors (BJTs). It refers to the flow of charge carriers from the emitter region of the transistor towards the base and collector regions. This current is a crucial component in the amplification process that transistors facilitate.
In an NPN bipolar junction transistor, the emitter is typically doped with N-type semiconductor material, meaning
For PNP transistors, the charge carriers are holes, and the doping types are reversed. The principle remains
