This illustration explains the working principle of a bridge rectifier. It shows how four diodes are connected in a bridge configuration to convert AC input into DC output. During the positive half cycle of the AC input, current flows through two diodes in one path, delivering power to the load. During the negative half cycle, the other two diodes conduct, again directing current through the load in the same direction. As a result, both half cycles of AC are utilized, producing a full-wave recti
