Hello all, I've read, and read, and read posts about this topic but I'm still confused. As someone new to hobby electronics I'd like to get this concept straight in my head before moving on. I believe the source of part of my confusion is the fact that we're told that current can't flow the wrong way through a Diode (LED). Yet many of the schematics shown on the internet show electron flow through the pointed end of a Diode. I thought this was a no-no? This logic is what's confusing me, not the arbitrary sign convention. I have no problem with a sign convention as long as it's used consistently. My problem is thinking about electron flow and seeing schematics on the internet that seemingly shouldn't work at all. When people say that it doesn't matter which way the current is assumed to flow, this just further confuses me. It seems like it would absolutely have to matter in the design and placement of components! What am I missing here? Please help!
