ElectroBOOM explaining the full-bridge rectifier
> The 60-Hertz AC (alternating current) from the wall oscillates 60 times a second, but the power supply needs steady DC (direct current) that flows in one direction. The full-bridge rectifier [1] below converts the AC to DC. [1] this video I just knew which video is linked without clicking. ElectroBOOM is a treasure.

Lighthearted take on full bridge rectifiers from ElectroBOOM
Not sure if HN knows about Mehdi Sadaghdar's (aka ElectroBOOM's) YouTube channel, which is somewhat similar - but takes a more lighthearted view on electronics. E.g. Compare Big Clive's mention of a full bridge rectifier in the video vs Mehdi's YouTube video of the same thing :) this video
