Red LED Pictorial Showing Anode and Cathode along with Schematic Symbol

An LED has a positive (Anode) lead and a negative (Cathode) lead. The schematic symbol of the LED is similar to the diode except for two arrows pointing outwards. The Anode (+) is marked with a triangle, and the Cathode (-) is marked with a line.

The longer lead of an LED is generally the positive (Anode), while the shorter lead is the negative (cathode).
