Bridge Rectifier: Ever wondered how those mysterious four diodes can turn alternating current (AC) into direct current (DC)? It’s like a superhero quartet saving the day in the world of electronics! Let’s demystify the magic of bridge rectifiers.

Bridge Rectifier Formula

DC Voltage (V_dc) = Peak AC Voltage (V_peak) * 0.9

Behold the electrifying formula for calculating the DC voltage (V_dc) output by a bridge rectifier, where Peak AC Voltage (V_peak) is the key player. Now, let’s explore the wattage wonders of bridge rectifiers.
