Current Only Flows in One Direction through a Diode
- A diode is a special device made from semiconductor material such as silicon.
- It is used to regulate the potential difference in circuits.
- It lets current flow freely through it in one direction, but not in the other.
- This turns out to be real useful in various electonic circuits.
Light-Emitting diodes are Very Useful
- A LED emits light when a current flows through it in a forward direction.
- LEDs are being used more…
