A diode is a semiconductor device that converts AC to DC current through rectification. It uses a PN junction with positive and negative connections, providing unidirectional conductivity. In operation, current can flow from the anode (positive side) to the cathode (negative side) and is blocked in the reverse direction. This makes the diode a simple and reliable rectifier for converting alternating current to direct current in circuits.
