A diode is a two-terminal electronic component that essentially acts as a one-way switch for current. It has low resistance in one direction, and high resistance in the other.

Diodes are also known as rectifiers because they change alternating current into pulsating direct current. Diodes are rated according to their type, voltage, and current capacity.
