What circuit can be used to set the conduction time of semiconductors in power-control circuits?
A) RC filter
B) Oscillator
C) Regulator
D) Phase-shifter

Question

Quizplus · Accepted Answer

A phase-shifter is used to adjust the phase angle of the AC supply voltage in power-control circuits, which in turn sets the conduction time of semiconductors like thyristors or triacs, allowing for precise control over the power delivered to the load.
