Conversion of alternating current into direct current is called:
Correct answer: A. Rectification
- A. Rectification
- B. Amplification
- C. Oscillation
- D. Regeneration
Explanation
Rectification is the correct answer because it specifically refers to the conversion of alternating current (AC) into direct current (DC). This process is essential in many electronic devices that require a stable DC supply from an AC source. Amplification is incorrect because it pertains to increasing the strength of a signal, not converting it. Oscillation is incorrect as it describes a repetitive back-and-forth motion, not a conversion process. Regeneration is incorrect because it is not related to electrical circuitry or processes.

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.
