A half-wave rectifier uses:
Correct answer: A. One diode
- A. One diode
- B. Two diodes
- C. Three diodes
- D. Four diodes
Explanation
RECTIFICATION:The conversion of AC into DC is called the rectification.RECTIFIER: A device used for rectification is called rectifier.TYPES:Half-wave rectifier: A halfwave rectifier is defined as a type of rectifier that allows only one-half cycle of an AC voltage waveform to pass while blocking the other half cycle. Full-wave rectifier: A full wave rectifier is defined as a rectifier that converts the complete cycle of alternating current into pulsating DC. A half wave rectifier uses only one diode for the transformation.Hence option A is correct. OPTION A:A half wave rectifier uses only one diode for the transformation.Hence option A is correct.OPTION B: A center tapped full wave rectifier is a type of rectifier which uses a center tapped transformer and two diodes to convert the complete AC signal into DC signal.OPTION C: This option is incorrect also. OPTION D: The bridge rectifier is a type of full-wave rectifier that uses four or more diodes in a bridge circuit configuration to convert alternating (AC) current to a direct (DC) current.

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.
