A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The process is known as rectification, since it "straightens" the direction of current. Physically, rectifiers take a number of forms, including vacuum tube diodes

How to Use a Rectifier Diode. Rectifier diodes allow current to flow in only one direction, from anode to cathode, also called Forward Bias. The rectifier diode in forward bias is made by connecting the anode to the most positive side and the cathode to the most negative side. You can see this in the example below:
