which of the following components converts ac to dc?

The component that converts AC to DC is a rectifier , which is typically built using diodes that allow current to flow in only one direction, turning alternating current into (pulsating) direct current.

Quick Scoop: Direct Answer

If your question is a multiple-choice like “Which of the following components converts AC to DC?”, the correct choice is:

• Rectifier (diode rectifier circuit).

A rectifier is usually made from diodes , because diodes only conduct in one direction, so they effectively “clip off” one half of the AC waveform and produce a one‑directional current.

Mini Explanation (Very Short)

• AC (alternating current) changes direction periodically.
• DC (direct current) flows in only one direction.
• A rectifier circuit uses diodes to let current pass in only one direction, converting AC into DC that can then be smoothed with capacitors into a more stable output.

So, among typical options like “transformer, rectifier, filter, regulator,” the answer is rectifier.
