A: LED will have a visual greater real estate on the cathode side it can be seen if the LED is transparent other way is using a VOM and measure the potential . the less potential will be at the cathode.
a nonsense question
Yes
The side of any diode that must be negative in order for the diode to conduct is the "cathode".
The end marked with a band is the cathode.
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.
The forward current of an LED is current that goes from the anode of the LED to the cathode (the forward direction).
Anode and cathode. Anode = negative lead, cathode = positive lead.
Cathode and an anodeThey are called the "anode" and the "cathode", just like every other diode ever built.
Current flows from the anode (positive terminal) to the cathode (negative terminal) in a LED. The longer leg of the LED indicates the positive anode side, while the shorter leg represents the negative cathode side.
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.
The charge of the particle in cathode rays is negative. This was determined by J.J. Thomson through his experiments with cathode ray tubes in the late 19th century, which led to the discovery of the electron.
