What does "Full Wave Rectification" mean?

Full Wave Rectification refers to a process in which both halves of the AC (alternating current) waveform are utilized to produce a DC (direct current) output. In this context, the term "full wave" highlights that the rectification captures the entire AC cycle, effectively converting both the positive and negative portions into usable DC.

Specifically, during full wave rectification, when the AC waveform goes positive, it is allowed to pass through, and when it goes negative, it is flipped to also be positive. This results in a smoother and more consistent DC output than what is produced by partial or half wave rectification, which only utilizes one half of the AC cycle. Therefore, the correct answer effectively captures the essence of how full wave rectification functions, as it highlights the conversion of the negative part of the AC cycle to positive DC voltage, contributing to a more stable and continuous DC signal.
