A diode in half-wave rectifier produces output for:
AContinuous
BOnly one (positive) half cycle of AC; other half blocked
CBoth half cycles
DDC always
Answer & Solution
Correct answer: B. Only one (positive) half cycle of AC; other half blocked
Half-wave: single diode conducts only when AC is in forward direction; reverse half cycle blocked. Output: pulsating DC with gaps. Efficiency low. Full-wave uses 2 diodes (or bridge of 4) for both halves.
