Solution:
- The full form of LED is Light Emitting Diode.
LED:
- It is an optical semiconductor device that emits light when voltage is applied means it converts electrical energy into light energy.
- Light Emitting Diode (LED) works only in forward bias conditions.
- When Light Emitting Diode (LED) is forward biased, the free electrons from the n-side and the holes from the p-side are pushed towards the junction.
- Light-emitting diodes emit either visible light or invisible infrared light when forward biased.
- The LEDs which emit invisible infrared light are used for remote controls.
- LEDs that can emit red, yellow, orange, green and blue light are available for commercial use.
