What is diode? Why use in circuit

Question

Accepted Answer

A diode is a semiconductor device that allows current to flow in one direction only. It is used in circuits to control the direction of current flow and to rectify AC to DC.

Diodes are used to protect circuits from reverse polarity, preventing damage to sensitive components.
They are used in rectifier circuits to convert AC voltage to DC voltage, such as in power supplies.
Diodes are also used in signal processing circuits, such as in radio frequency detectors.
They can be used in voltage regulation circuits to maintain a stable output voltage.
Diodes are essential components in many electronic devices, from simple LED lights to complex computer systems.
