Reply to "How About A LED Primer?"

I agree that I was incorrect about the typical forward voltage of an LED and that has been fixed above. I agree that the resistances I came up with in my example are extreme as a result of my low forward voltage.

However, unless I was able to foresee the applications of all the people reading this in the future and posted all of those answers, any single answer would be "false". Hence why I gave the formula and showed them how to calculate it themselves - in my opinion that's the important part, not the example.
