Dans un transistor à effet de champ, quelles deux électrodes sont raccordées aux extrémités du canal?
- ALa source et la base
- BLa source et le drain
- CLa source et la porte
- DLa porte et le drain
Correct answer: B — La source et le drain. Question tirée de la banque officielle d'ISDE.
Why
In a field-effect transistor, the channel is the path where electricity flows, and this path runs directly between the source, where carriers enter, and the drain, where they exit. The full explanation — and one for every question — is in Pro.
