Solid-state relays intended for use as AC controllers have a ____ connected to the load circuit in place of a power transistor.
A) diac
B) sidac
C) thyristor
D) triac

Question

Quizplus · Accepted Answer

Triacs are commonly used in solid-state relays for AC control because they can switch both halves of the AC waveform and are able to latch on once triggered. Diacs and sidacs are not commonly used as switches in AC controllers, and thyristors only switch one half of the waveform.
