What is full mean of LED?

Light Emitting Diode
The term ‘LED’ stands for Light Emitting Diode. This is a semiconductor source of light that emits bright light when the electricity passes through it.

What is LED Class 12?

A light emitting diode (LED) is a forward biased p-n junction diode That emits visible light when energized. When light emitting diodes are forward biased, the electrons from the n-type material cross the p-n junction and recombine with holes in the p-type material.

What is the full form of LED & LCD?

Light emitting diode display (LED) Liquid-crystal display (LCD)

What is the full form of LED Class 7th?

The full form of LED is Light Emitting Diode.

What is LED computer science 10?

Answer: Explanation: Definition: The LED is a PN-junction diode which emits light when an electric current passes through it in the forward direction. The LED is made of semiconductor material which is colourless, and the light is radiated through the junction of the diode.

What is LED class 10th?

A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it.

What is LED and its working?

Working Principle: A light-emitting diode is a two-lead semiconductor light source. It is a p–n junction diode that emits light when activated. When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons.

What is the full form of LCD and LED and CRT?

CRT-Cathode ray tube. LCD-Liquid Crystal display. LED-Light Emitting Diode.

What is the full form of LED and MCB?

LED = Light Emitting Diode. 2. LCD = Liquid Crystal Display. 3. MCB = Miniature Circuit Breaker.

What is the full form of LED Class 8?

The full form of LED is Light Emitting Diode.

What is full form of CFL and LED?

Since 2014, government regulations have been pushing consumers to replace familiar incandescent light bulbs with more energy-efficient compact fluorescent lamp (CFL) and light-emitting diode (LED) bulbs.

What is LED and its working principle?

What is the full form of led led?

What is the full form of LED LED: Light Emitting Diode LED stands for Light Emitting Diode. It is a two-lead semiconductor light source.

What is the light produced by led?

A light-emitting diode (LED) is a semiconductor device that emits visible light when an electric current passes through it. The light is not particularly bright, but in most LEDs it is monochromatic, occurring at a single wavelength. The output from an LED can range from red (at a wavelength of approximately 700 nanometers) to blue-violet

What is the meaning of LED light emitting diode?

light-emitting diode (LED) Also see laser diode. A light-emitting diode (LED) is a semiconductor device that emits visible light when an electric current passes through it. The light is not particularly bright, but in most LEDs it is monochromatic, occurring at a single wavelength.

What happens when current passes through an led?

When current passes through the LED, the electrons recombine with holes emitting light in the process. It is a specific type of diode having similar characteristics as the p-n junction diode.
