1.	In a transistor why is the base made thin in comparison to the emitter and collector?
Answer» The base of a transistor is kept very thin compared to the collector and emitter so that most of the carriers (carriers means electron in case of npn transistor and holes in case of pnp transistor) pass to the collector, injected from the emitter i.e, less number of electron-hole recombination take place and whole current emitted from emitter with a slight difference is passed to the collector.
