A Bridge Rectifier 2A is an electronic component used to convert AC (Alternating Current) into DC (Direct Current) using four diodes arranged in a bridge configuration. The “2A” rating means it can safely handle up to 2 amperes of current during operation. When AC is applied to the input of the bridge, the diodes conduct in pairs during each half cycle, ensuring that the output always flows in the same direction. This produces a pulsating DC voltage, which is usually smoothed further with a capacitor to provide a more stable DC supply. A 2A bridge rectifier is commonly used in power supply circuits for small electronic devices, battery chargers, adapters, LED drivers, and other low-to-medium current applications. It is available in compact packages (such as round or square black plastic casings with 4 pins marked with “~” for AC input, “+” for positive DC, and “–” for negative DC).
