Transistors (by alaric)

Now, my knowledge of electronics really centers around digital stuff, so transistors have always remained a bit of a mystery to me. Sure, I know the gate or base input controls stuff flowing between the other two oddly-named pins, but I've never really known how this works out in practice - if a 12v battery is placed betwixt the collector and emitter of an NPN transistor, and the base is supplied from the +12v rail via a 10KΩ resistor, what would happen?
