On March 13, 2014, physicsgal1 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.
Ohm's Law
V=IR
Series
V=ΣV=V1+V2+V3....
I=I1=I2=I3...
RT=ΣR=R1+R2+R3...
Parallel
V=V1=V2=V3....
I=I1+I2+I3...
RT=(R1-1+R2-1+R3-1)-1
or RT=(ΣR-1)-1
or 1/RT=[(1/R1)+(1/R2)+(1/R3)]-1
