What tools do you designers use to figure factors like voltage drop and power distribution during designs?
I have never used a calculator or a software tool for this. I always did it manually, and I wasn't especially consistent in calculating values. I just over-engineered (wasted money?) a lot following the precept "When in doubt, make it stout."
There has to be a better, easier method out there.
What tools do you use? Any nifty apps or websites to share?
