Question

In Electronic Terminology, 'LED' stands for
1. Light Emitting Device
2. Light Electronic Device
3. Light Emitting Diode
4. Light Electronic Diffuser

Answer 1

Correct Answer - Option 3 : Light Emitting Diode

The correct answer is Light Emitting Diode.

• In Electronic Terminology, 'LED' stands for Light Emitting Diode.
• Light Emitting Diode
  • It is a semiconductor light source that emits light when current flows through it.
  • It emits narrow bandwidth of either visible light at different coloured wavelengths, invisible infra-red light for remote controls or laser type light when a forward current is passed through them.
  • It has similar electrical characteristics to a PN junction diode. they have very similar electrical characteristics to a PN junction diode.
  • LEDs that can emit red, yellow, orange, green, and blue light are available for commercial use.
