thanks for the replies. <p>Cato, you made some interesting points here I'd like to understand. "The drop across the leds will vary all over the place from part to part..."<p>Why would this happen, does this happen because each part absorbs so much current based on it's properties?<p>"...

Oh, here's is a perfect example.. Why is this resistor needed here?<p>

Hi, I am new to electronics and I've read the basics to a point. <p>I always seem to get stuck on resistors after I see them on schematics. I know that, basically, they are used to drop the current... but!<p>Sometimes in the most simplest projects I see resistors in places where, even without them (...
