Answer Notes
Transistors generally have three main terminals: one that emits or sources the charge carriers, one that controls them, and one that collects or drains them. In a Field-Effect Transistor (FET), charge carriers enter the conducting channel through the "source" terminal.
In a Bipolar Junction Transistor (BJT), the equivalent terminal where charge carriers originate and enter the device is the "emitter".
To complete the analogy between the two devices: the FET's gate corresponds to the BJT's base (the control elements), and the FET's drain corresponds to the BJT's collector (where the carriers exit).
