A diode is a specialized electronic component with two electrodes called the anode and the cathode. Most diodes are made with semiconductor materials such as silicon, germanium, or selenium. Some diodes are composed of metal electrodes in a chamber evacuated or filled with a pure elemental gas at low pressure. Diodes can be used as rectifiers, signal limiters, voltage regulators, switches, signal modulators, signal mixers, signal demodulators, and oscillators.

Rectification
Rectification is the process of converting alternating current (AC) to direct current (DC). A diode is commonly used in rectifier circuits to allow current to flow in only one direction. This is achieved by utilizing the diode's property of allowing current to flow freely in one direction while blocking it in the opposite direction.
Explanation:
- When an AC signal is applied to a diode, it only conducts during one half of the AC cycle, allowing current to flow in one direction only.
- This results in the conversion of the AC signal into a pulsating DC signal.
- By using multiple diodes in a rectifier circuit, the pulsating DC signal can be further smoothed out to obtain a more stable DC output.
Not used for Purification
Purification typically refers to the process of removing impurities or unwanted components from a substance. In the context of electronics, purification does not directly relate to the function of a diode. Diodes are primarily used for rectification, regulation, switching, and protection in electronic circuits, but not for purification purposes.
Therefore, a diode is not used for purification.
