If it's a thru-hole LED, the anode is the longer pin.
If it's a used part and part had its pins cut off, the larger electrode inside is the cathode.

How can you identify a cathode nigative to an LED?
LED has two pins,one is anode(positive) and the other is cathode(negative).The smaller pin is cathode(negative) and the longer pin is anode(positive).
What types of anode?
the two types of anode is stationary anode and rotating anode
What is the difference between anode led and cathode led?
A: A LED is a diode and like all diode they have an [anode] meaning positive terminal and a [cathode] negative terminal. Therefore the proper potential must be applied for it to behave like an LED.
0n an LED what are the names of the positive and the negative leg?
Anode and cathode. Anode = negative lead, cathode = positive lead.
Forward current of led?
The forward current of an LED is current that goes from the anode of the LED to the cathode (the forward direction).
What happens if the long leg of LED is conected to a wire coming from the negative end of the dry cell?
The long leg of the LED is the Anode. Connecting the Anode to the negative end of the dry cell would bias the LED off. It would not illuminate. It may also destroy LED.
What is LED Forward Voltage?
The forward voltage of an LED is the voltage that must be applied across the leads of an LED, anode to cathode, in order for the LED to function and turn on.
What is the short and long legs of LED called?
Cathode (negative) is the shortest leg and there is a flat edge on the base of the LED, and it must be connected to the negative wire or "-" connection. Anode (positive) is the longest leg, and must be connected to the positive wire or "+" connection, as electricity will only pass through a LED from positive to negative.
What is the left leg of the led called?
Cathode and an anodeThey are called the "anode" and the "cathode", just like every other diode ever built.
How is the metal used in an anode different from the metal used in a cathode?
Anode is positive and cathode is negative. Cathode is the longest led frame. Anode is where the oxidation reaction takes place while cathode is where the reduction reaction takes place or in a galvanic corrosion the anode is the metal that corrodes while the cathode is protected.
The terminals of a diode are called the?
anode positive potential cathode negative potential
Why LED is used to determine planks constant?
led is used to determine Plancks constant
