WebThe symbol for an LED is shown in Figure. The basic operation of the light-emitting diode (LED) is as follows. When the device is forward-biased, electrons cross the pn junction from the n-type material and recombine with holes in the p-type material. Recall from Chapter 1 that these free electrons are in the conduction band and at a higher ... Webdiode, an electrical component that allows the flow of current in only one direction. In circuit diagrams, a diode is represented by a triangle with a line across one vertex. The most common type of diode uses a p-n junction. … WebThe symbol of an LED bears resemblance to that of a PN junction diode except for an arrow pointing away from the diode. This arrow is an indication that the diode is emitting light. The IV characteristics of an LED are identical to a diode with a forward biased condition. How do LEDs Work?
