Le redresseur commandé au silicium ("SCR") appartient à quelle grande catégorie de composants?
- AVaristors
- BThyristors
- CBoucles à phase asservie ("PLL")
- DVaractors
Correct answer: B — Thyristors. Question tirée de la banque officielle d'ISDE.
Why
The silicon controlled rectifier, or SCR, belongs to the thyristor family because it is a four-layer semiconductor device that acts as a switch, turning on when triggered and staying on until the current stops. The full explanation — and one for every question — is in Pro.
