What voiced consonant has the same active articulator as n and passive f?

The voiced consonant that has the same active articulator as /n/ and the same passive articulator as /f/ is the voiced labiodental fricative, /v/.

Here's why:

* Active Articulator: The active articulator is the part of the mouth that moves to create the sound. For both /n/ and /v/, the active articulator is the lower lip.

* Passive Articulator: The passive articulator is the part of the mouth that the active articulator moves against. For /n/ the passive articulator is the alveolar ridge, while for /v/ and /f/ it's the upper teeth.

Therefore, /v/ shares the active articulator with /n/ (lower lip) and the passive articulator with /f/ (upper teeth).
