LED CATHODE PLUS

NOTE: I took this picture myself from my camera, Please Do not mind for image clarity ,so i have put some labellings also. Fournissez ces lumires ultra-lumineuses des rsistances pellicule mtallique 1/4W, ce kit est pour l'utilisation la plus courante.Type d'objectif: Sommet de 5mm, ClairCouleur d'mission: Bi-couleur (et vert meraude)Tension directe: CC 1,8-2,0V 3,0-3,2 VCourant direct: 20 mARsistance: 430 Ohm (+/- 1)Polarit: Cathode communeLe forfait comprend:25 x LED, 25 x 430 Ohm. Before we learn about cathode and anode we need to first understand what an electrode is. The larger end inside the led is -ve and the shorter one is +ve, that is how we find out the polarity of a LED On the other hand, if you have a common cathode RGB LED, you need. microtivity 7-segment LED Display, 1 Digit Red Common Cathode (Pack of 4) details and prices. Insert the shorter lead (negative side, or cathode) into any hole in the nearby negative power. As they have to be crystall clear to glow so they don’t have any labeling on it, so the only way to know is either to test it with a multimeter or by carefully observing inside the led. If the LED lights up, this means you have a common anode LED. Building a single LED circuit on a breadboard is a snap. This longer lead is the anode (+), and the shorter one is the cathode (-). Beschikbaarheid: Direct leverbaar uit magazijn in Eindhoven. Notice the picture carefully and compare it with the LED diode symbol, that should tell which one is –ve and +ve terminal. The first is that LEDs have one lead that is longer that the other. I hope the figure below can solve this problem of identification.

LED's or Light Emitting Diode's don’t come with any labeling on it to identify Cathode(-ve,GND) or Anode(+ve). Sometime the diode symbol creates confusion too.Identifing a LED's the cathode and anode of a led is very easy by looking inside. Denotes the voltage generated between the anode and cathode when forward current is applied. So for identification, led’s comes with a unique way to identify its terminals as Anode or Cathode. While referring to any schematic involving led's we sometimes get confused with the identification of the terminals.
