In half wave rectification the output DC voltage is obtained acrossthe load for:
Correct answer: B. The positive half cycle of input AC
- A. The negative halfcycle of input AC
- B. The positive half cycle of input AC
- C. Both the input of AC
- D. None of the above
Explanation
The half-wave rectifier is a rectifier that allows one-half of the AC voltage signal and blocks the other half, and converts AC voltage to DC voltage, so we obtain the pulsating DC voltage as an output signal. A single diode works for a single-phase supply, but in the case of a three-phase supply, three diodes are needed. Only half of the input waveforms reach the output, so three diodes are needed. By adding more filters in the half-wave rectifier circuit, the rippling of the AC frequency from the output can be reduced.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
