Parmi les composants suivants, lequel a une anode, une cathode et une gâchette (ou porte)?
- ALe transistor bipolaire
- BLe transistor à effet de champ
- CLa triode à vide
- DLe redresseur commandé au silicium ("SCR")
Correct answer: D — Le redresseur commandé au silicium ("SCR"). Question tirée de la banque officielle d'ISDE.
Why
The silicon controlled rectifier (SCR) is the only device listed with an anode, cathode, and gate because it acts as a switch that turns on when a small signal hits the gate and stays on until the current stops. The full explanation — and one for every question — is in Pro.
