In a half wave rectifier, the output

Correct answer: B. consists of one half cycle only, with the other half missing

  • A. uses both halves of the input cycle
  • B. consists of one half cycle only, with the other half missing
  • C. is a steady direct voltage
  • D. is zero

Explanation

The single diode conducts only while its anode is positive, so alternate half cycles are blocked and the output is a series of pulses with gaps between them. This makes it inefficient and hard to smooth, since the ripple frequency is only that of the supply. A full wave rectifier inverts the other half instead of discarding it.

About Rectification

Rectification converts alternating current into unidirectional current using semiconductor diodes. The content includes half wave and full wave rectifiers, bridge circuits, output waveforms, ripple and smoothing with capacitors, with the difference between rectification and voltage regulation kept clear.
