Define Bipolar Junction Transistor.
Three-terminal semiconductor that amplifies or switches electronic signals.
What is done during manufacturing of a transistor that determines the current flow through the diode?
Doping.
What are the three conditions that a transistor will operate at?
Cutoff, saturation, and active region.
When a transistor is being used as a switch, what two conditions determine the operation?
Cutoff (off state) and saturation (on state).
