This simulation illustrates the operation of a bridge rectifier converting a 60 Hz AC supply (blue waveform) into pulsating DC. Four diodes are arranged in a bridge configuration with a 1 kΩ load resistor. The green waveform shows the output during the negative half-cycle, and the yellow waveform shows the output during the positive half-cycle. In both cases, the bridge directs current through the load in the same direction, producing the red waveform—the load current—which has twice the frequen
