Le rôle principal d'une diode Zener est:
- Ade fournir un déphasage de tension
- Bd'augmenter la tension du bloc d'alimentation
- Cde fournir un trajet par lequel le courant peut circuler
- Dde réguler une tension, c'est-à-dire la maintenir constante
Correct answer: D — de réguler une tension, c'est-à-dire la maintenir constante. Question tirée de la banque officielle d'ISDE.
Why
A Zener diode is designed to hold a specific voltage steady even when the current flowing through it changes, making it ideal for regulating or maintaining a constant voltage in a circuit. The full explanation — and one for every question — is in Pro.
