A triac must be triggered for each alternation for proper operation.

Question

Quizplus · Accepted Answer

Triacs are devices that can control AC voltage and current. They are typically triggered by a low-power signal, such as a pulse or voltage across a gate-cathode junction. For proper operation, the triac must be triggered at the beginning of each alternation of the AC signal, which occurs 50 or 60 times per second depending on the country's power grid. If the triac is not triggered for each alternation, it may not function properly, leading to issues such as incomplete dimming or voltage regulation.
