Question

For NPN transistor in active mode, base-emitter junction is ___ and base-collector is ___:

Accepted Answer

D. Forward and reverse — BE forward, BC reverse (active region)

**Active mode:** BE forward bias (inject electrons into base), BC reverse bias (collect electrons that diffuse across thin base region).
Both forward = saturation; both reverse = cutoff.

Answer

Both off

Answer

Both forward

Answer

Both reverse

For NPN transistor in active mode, base-emitter junction is _ and base-collector is _:
