Quel est le rapport alpha d'un transistor bipolaire en montage base commune?
- ARapport de transfert (gain) direct en tension
- BRapport de transfert (gain) inverse du courant
- CRapport de transfert (gain) inverse en tension
- DRapport de transfert (gain) direct du courant
Correct answer: D — Rapport de transfert (gain) direct du courant. Question tirée de la banque officielle d'ISDE.
Why
Alpha measures how much the output current in a common base setup follows the input current, making it a forward current gain because the signal moves from emitter to collector. The full explanation — and one for every question — is in Pro.
