WebThe NPN transistor has a lot of doping. The majority of carriers travel in the direction of the base when the prestress is placed on the transmitter. This is the result of the current EI of the transmitter. The holes and electrons mix in the material P. The NPN transistor base has a little doping. Therefore, only a small number of electrons are ... WebAn NPN transistor is one in which the majority of the current carriers are electrons. Electron flowing from the emitter to the collector forms the base of the majority of current flow through the transistor. The further types of charge, holes, are a minority. PNP transistors are the opposite. In PNP transistors, the majority of current carrier ...
