For a transistor in CE mode to be used as an amplifier, it must be operated in:
Answer: (C) The active region only
Amplification needs the output current to follow the input linearly, which happens only in the active region (emitter-base forward biased, collector-base reverse biased). Cut-off and saturation are used for switching.
