It is my understanding a LED needs direct current to work.
I have small LEDs which came from a 3v Walmart Christmas light string.
I have a resistor in series and was going to put a small diode in series to protect the LED.
I am using a 13v AC transformer.
It doesn't make any difference which direction I put the diode in the circuit, in fact, the LED works fine witout the diode.
Am I doing something wrong, or is my understanding incorrect?
