Answer / tyson boundy

A light-emitting diode (LED) is a two-lead semiconductor light source. It is a p–n junction diode, which 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. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconducto

Answer / pragathi tripathi

LED stands for Light Emitting diode.That means it emitts light when it is connected in Forward bias.An LED can emitts different colour of light.for example the LED made up of AL, GA, AS, emitts red colour light.LED made up of GA,P emitts Green colour.LED made up of GA,AS,P will emitts yellow clour light

Answer / mukesh pellargade

LED STHNDS FOR LIGHE EMITTING DIODE AND IT IS ONLY USE FOR TO EMITTING THE LIGHT WHEN IT IS FORWARD BIAS. IT TWO TERMINAL ANODE AND CATHOPDE ANODE HAS POSITIVE AND CATHODE HAS NEGATIVE.AND WHEN THE POSITIVE SUPPLY TO THE ANODE AND NEGATIVE SULLPY PROVIDE TO THE CATHODE THEN AND THEN ONLY LED EMITTES THE LIGHT DEPENDION COLOURS.
