Have you ever seen those cards that some "electrical

V = I * R
R = V / I
I = V / R

I found it:

Unbelievable. The author of it writes:
"I'm going to explain to you how to use this cheat sheet in
case you've never seen this before."

Makes you want to cry.
No real electrical engineer would ever use that card, as you
connote with your quotes. If they don't have Ohm's law and the
resulting algebra drilled into their head, they better find
another job. I suspect that chart is for amateurs from other
backgrounds who happen to be doing some electrical work.
Screw engineers, *anybody* who doesn't know these laws shouldn't
be allowed anywhere *near* electricity :D
