Question : Transistor operation
Correct answer: One of the PN junctions will be forward
biased and the other will be reversed biased
Question : Emitter-Base Junction (BJT)
Correct answer: Forward biased operation. This current flow
is known as majority flow where holes flow from the emitter and electrons flow from the base.
Question : Collector-Base Junction (BJT)
Correct answer: Reverse biased operation. Small current flow
across the junction known as minority current carriers. Holes flow from the base and electrons flow from the collector.
Question : Collector cutoff current(Ico or Icbo)
Correct answer: The minority current carriers are known as
collector cutoff current(Ico or Icbo) since they flow across a reverse-biased, or cutoff junction.
Question : An amplifier increases the strength of ______,
_______, or ________ of a signal
