Dans un redresseur commandé au silicium ("SCR"), quel nom donne-t-on à l'élément de contrôle?
- AGâchette (porte)
- BAnode
- CCathode
- DÉmetteur
Correct answer: A — Gâchette (porte). Question tirée de la banque officielle d'ISDE.
Why
The gate acts as the small switch that turns the silicon controlled rectifier on, allowing current to flow from the anode to the cathode only when a signal arrives at this specific terminal. The full explanation — and one for every question — is in Pro.
