⚙️ How a 5mm LED Works

A Light Emitting Diode (LED) is a semiconductor device that emits light when electrical current flows through it. When forward voltage is applied, electrons recombine with holes inside the semiconductor material, releasing energy in the form of light.

LEDs are very efficient and require minimal current compared to traditional lighting components.

To safely use LEDs in circuits, they must be connected with a current-limiting resistor.
