technology medium true_false

A transistor can function both as a switch and as an amplifier in electronic circuits.

  1. True
  2. False

Answer: True

Transistors operate in three regions: cutoff (OFF switch), saturation (ON switch), and active (amplifier). In digital circuits, they switch between cutoff/saturation for binary logic. In analog circuits, active region amplifies weak signals. Fundamental building block of modern electronics from microprocessors to power controllers.
