Dans un transistor à effet de champ, par quelle électrode les porteurs de charge entrent-ils dans le canal?
- AL'émetteur
- BLa source
- CLa porte
- DLe drain
Correct answer: B — La source. Question tirée de la banque officielle d'ISDE.
Why
In a field-effect transistor, the Source is the electrode where charge carriers enter the channel to flow toward the other end. The full explanation — and one for every question — is in Pro.
