What I have learned about LED


One of the first things I learned was that Led stood for Light Emitting Diode. I also learned was that for an LED light to work, the circuit it is connected to must be closed so that it is a complete cycle. Another thing that I learned was that with the LEDs we were using, no matter how many batteries were being used to power the LED, the light did not become any brighter. I learned that the longer wire-type thing is the positive side and the shorter one is the negative.
