A light-emitting diode (LED) is a semiconductor device that emits light when an electric current passes through it. It works on the principle of electroluminescence, where the movement of electrons within the semiconductor material releases energy in the form of photons (light). What are the typ...
A Light-Emitting Diode (LED) is a small component that lights up when there is current flowing through it. It’s used in light bulbs, displays, lighting decorations, and much more. In electronics, it’s often used for showing the state (is the gadget turned on?). You can see the lig...
