A diode is a simple electronic component that allows electric current to flow in one direction only. It acts like a one-way valve for electricity.
It has two terminals:
- **Anode (positive side)**
- **Cathode (negative side)**
When the positive side (anode) is connected to a higher voltage than the negative side (cathode), the diode conducts electricity. This is called **forward bias**. But when the voltage is reversed (anode is negative compared to cathode), the diode blocks the current, known as **reverse bias**.
Diodes are widely used in circuits for rectification (turning AC to DC), protection against voltage spikes, and signal processing, among other applications.
Some common types of diodes are:
- **LED (Light Emitting Diode):** Emits light when current flows through it.
- **Zener Diode:** Allows current to flow in both directions but only allows voltage to pass in the reverse direction once it reaches a certain threshold.
It’s a key component in many electronic devices!
