A diode is an electronic component that allows current to flow in one direction while blocking it in the opposite direction. It is a fundamental building block in many electronic circuits.
Diodes are used in power supplies, signal processing, and protection circuits. They are essential in devices that require controlled current flow and stable operation.
A diode conducts electricity when it is forward-biased and blocks current when it is reverse-biased. This allows it to act as a one-way valve for electrical current.
In a power supply, diodes are used in rectifiers to convert AC power into DC power for medical devices.
