If 1% electrons are lost in the base, the fraction of current that enters … Web1) The essence of an NPN transistor is that it is not just 2 PN diodes in anti series (like NP - PN ) but an NPN structure where the P-layer is quite thin. So what happens is that the electrons coming from the emitter (at some speed) while traveling through that very thin base, have a large chance of going too far and ending up in the collector.
