Diodes are used in electrical power supply circuits primarily as

Explanation:
Diodes in power supply circuits are used to rectify AC into DC. They conduct in only one direction, so during the positive half-cycle they pass current while blocking the negative half-cycle, creating a pulsating DC output. Arranging diodes in a bridge or other rectifier configuration lets you convert nearly all of the AC waveform into usable DC, which is then smoothed by filters to provide stable power for electronics. While transistors, inductors, and capacitors play other roles in regulation and filtering, the primary purpose of diodes here is rectification.
