Dans un transistor à effet de champ (MOSFET) à enrichissement avec canal N, la circulation des électrons est associée à :
- Al'enrichissement du canal N
- Bl'appauvrissement du canal Q
- Cl'enrichissement du canal P
- Dl'appauvrissement du canal P
Correct answer: A — l'enrichissement du canal N. Question tirée de la banque officielle d'ISDE.
Why
In an n-channel enhancement MOSFET, the device starts with no path for electrons to flow until a positive voltage is applied to the gate, which creates or "enhances" a conductive channel. The full explanation — and one for every question — is in Pro.
