William Shockley, one of the inventors of the transistor, once explained transistor-amplifiers this way:
>*”If you take a bale of hay and tie it to the tail of a mule and then strike a match and set the bale of hay on fire, and if you then compare the energy expended shortly thereafter by the mule with the energy expended by yourself in the striking of the match, you will understand the concept of amplification.”*
which seems to describe the concept but not the process.

The base is the middle junction of the transistor and acts as a valve between the end junctions, collector and emitter. A small current from base-to-emitter opens the valve and allows a much larger current to flow collector-to-emitter. Think of a valve at the bottom of a damn. The force to open the valve can be very small in relation to the force released.
