Looks like a good site for info. The one thing about an LED that you have to remember is that it is not so much an electrical "load" like a light bulb, but more like an electrical switch that closes when the polarity of the voltage is correct. That is why the LED requires a resistor in series. The eresistor is the "load" in the circuit. Without it, we basically have a short circuit and the switch (LED) will burn up... just like a light switch.
