I know this question is very vague, but my textbook, amongst various websites/videos, tend to discuss what a transistor does (amplify/control current) rather than how it does it. I know current IC and IE (collector and emitter current) are controlled/proportional to a base current that flows through the base of a transistor, but what is most confusing is that my textbook says a transistor amplifies current, how is this so? From what it seems to me, a transistor looks like a gateway that splits, in one way or another, emitter current into both base current and collector current, but isn't that to say that collector current is the deduction of base current from emitter current, rather than an amplification?
Any help would be appreciated.
