What is characteristic of a half-wave rectifier in a power supply?
Only one diode is required✓الإجابة الصحيحة
The ripple frequency is twice that of a full-wave rectifier
More current can be drawn from the half-wave rectifier
The output voltage is two times the peak input voltage
الشرح
A half-wave rectifier passes only one polarity, so a single diode is all it needs. That produces one output pulse per input cycle, making the ripple frequency equal to the line frequency; twice the line frequency is a property of full-wave rectification.
