Pour qu'une diode conduise, elle doit être:
- Aen polarisation inverse
- Ben polarisation directe
- Ccouplée d'une façon rapprochée
- Denrichie
Correct answer: B — en polarisation directe. Question tirée de la banque officielle d'ISDE.
Why
A diode acts like a one-way valve for electricity, and it only opens to let current flow when you apply voltage in the direction that pushes electrons through it. The full explanation — and one for every question — is in Pro.
