In order to identify the ANODE and CATHODE this would normally be identafiable by a bar going around the diode.
A diode has the characteristics of a INSULATOR when current tries to flow in the 1 direction or a CONDUCTOR when the current flows in the other.
The Anode end is represented by the + sign and the Cathode by the - sign in the diagrams provided above
Below is the LIGHT EMMITING DIODE more commonly known as the L.E.D
L.E.Dz are reasonabally easy to distinguish the difference between the Anode Cathode sides..the Cathode side generally has a shorter leg to the Anode,.
