The two main types of diodes are:
Rectifier Diode: This type of diode is primarily used in rectifier circuits to convert alternating current (AC) into direct current (DC). Rectifier diodes allow the current to flow in one direction (forward-biased) while blocking it in the opposite direction (reverse-biased). They are commonly used in power supplies, battery charging circuits, and other applications where AC to DC conversion is necessary.
Light-Emitting Diode (LED): LEDs are a special type of diode that emits light when current passes through it in the forward direction. They are commonly used in various applications, such as indicator lights, displays, illumination, and even in optoelectronic communication devices.
These two types of diodes serve different purposes but are essential components in a wide range of electronic circuits and devices.
