Reference Answer
The difference between half wave and full wave rectification:
Half-wave rectification:
Uses a single diode to allow only one-half of the AC waveform (either the positive or negative half-cycle) to pass through. The other half is blocked.
Results in a pulsating DC output with a significant amount of ripple (variation in voltage). The average DC voltage is lower compared to the input AC voltage.
