The three terminals of BJT are the base, emitter and collector. A very small current flowing between the base and emitter can control a larger flow of current between the collector and emitter terminal.

field which
grows
continuously
with ever
expanding
frontiers. “The combined results of several people working together
is often much more effective than could be that of an
individual scientist working alone.”
