Main Question or Discussion Point

ive been reading about transistors and i have a question i cant find answer to, maybe someone here knows the answer. how much current can a transistor amplify or create? for example, can you push 1 amp of current through the collector of a 15 amp 12 volt NPN transistor and would it boost the current to 15 amps coming out of the emitter?

No.
A transistor can be thought of as a current controlled variable resistor.

Collector current is determined by base current times the transistor gain.
Emitter current will be collector current + base current.
