The silicon controlled rectifier (SCR) is a member of which family?
- A Thyristors
- B Phase locked loops
- C Varactors
- D Varistors
Correct answer: A — Thyristors. From the official ISED question bank, verified word for word.
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.
