Subsection 4.2.10 Diodes

A diode is an electrical component that allows current to flow in one direction while blocking it in the opposite direction. It acts as a “one-way valve” for electric current. Diodes are made from semiconductor materials and have two terminals: an anode (positive side) and a cathode (negative side).

Rectifier Diodes are used for converting AC to direct current DC (rectification).

Zener diodes are used for voltage regulation and voltage reference applications. They maintain a nearly constant voltage across their terminals regardless of current changes.

Light Emitting Diodes (LEDs) emit light when current flows through them. They are used for indicators, displays, lighting, and optical communication.
