Une diode Zener est un composant qui sert à :
- Astabiliser une tension
- Bdissiper une tension
- Cdiminuer un courant
- Daugmenter un courant
Correct answer: A — stabiliser une tension. Question tirée de la banque officielle d'ISDE.
Why
A Zener diode is designed to maintain a steady voltage level across its terminals, even when the current flowing through it changes, which is the definition of regulating voltage. The full explanation — and one for every question — is in Pro.
