In a half wave rectifier, the diode conducts:
Correct answer: A. Only positive half of input cycle
- A. Only positive half of input cycle
- B. Only negative half of input cycle
- C. Both halves of input cycle
- D. Any one half of input cycle
Explanation
In a half-wave rectifier, the diode conducts during the only positive half of the input cycle. During the negative half of the input cycle, the diode is reverse biased and does not conduct. Therefore, only the positive half of the AC input is converted to DC output. The negative half of the input is blocked. This is the fundamental operation of a half-wave rectifier.

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.
