The device or circuit used for conversion of A.C. into D.C. is called_______________?
Correct answer: B. A rectifier
- A. An amplifier.
- B. A rectifier
- C. Filtering circuit
- D. Converter.
Explanation
A rectifier changes alternating voltage or current into a unidirectional, pulsating DC output, usually by using diodes. A filter may smooth the rectified output, but it does not itself perform the AC-to-DC conversion. The likely mistake is choosing converter because it is a general term, whereas rectifier is the specific circuit name.

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.
