[Re:] Circuits

mentioned learning about circuits, Ohm's Law, a few formulas she learned and even referrenced a video regarding circuits.

Now that I'm understanding circuits and how to do VIP charts I really enjoy doing them. To me, the process has become almost medative-at least once I get going. I found the video helpful as it reminded me that the electrions technically flow from the negative side to the positive. Part of me wishes I had looked for a video, like the one referrenced, earlier in the course of learning. Another part of me is glad I didn't because I got to learn the process
(a little)
on my own and I feel like I know the concept better now because I did the work/learning myself.

Now maybe this is just my personality and desire to keep everything organized and together but I would not have only three equations in that post. Even if I know/knew all the equations, I'd rather put all of the ones for series (and parallel) down just in case I
do
end up forgetting them. Plus, doing so "proves" I know what I'm doing and leaves little room for others to doubt me but that's just how I operate.
