Dans un transistor à effet de champ, par quelle électrode les porteurs de charge sortent-ils du canal?
- ALe collecteur
- BLa source
- CLa porte
- DLe drain
Correct answer: D — Le drain. Question tirée de la banque officielle d'ISDE.
Why
In a field-effect transistor, the channel acts like a pipe where charge carriers flow in from the Source and exit through the Drain, much like water draining from a sink. The full explanation — and one for every question — is in Pro.
