NettetA “Light Emitting Diode” (LED) is a variant of the standard diode with the same characteristics. The obvious difference is that when current flows through an LED it generates visible (non-visible) light. When looking at the specifications for a LED, there are two key ratings to note: the “Forward Voltage” and the “Forward Current.”.
