Is anode or cathode positive or negative? [Answered!]

WitrynaLEDs are diodes which are elecronic devices that only allow current to go through them in one direction. This means that LEDs (and other diodes) have positive (+) and … WitrynaThe positive side of the LED is called the "anode" and is marked by having a longer "lead," or leg. The other, negative side of the LED is called the "cathode." Current flows from the anode to the cathode and never the opposite direction. A reversed LED can keep an entire circuit from operating properly by blocking current flow. WitrynaWhen this is done, "anode" simply designates the negative terminal of the battery, "cathode" the positive terminal. In a diode, the anode is the terminal represented by the tail of the arrow symbol (flat side of the triangle), where … michael paige bentley
