I'd be curious for you to expand on your very last statement.
I assume that refers to:
BTW, putting absolute value bars around one side or
the other in Ohm's law is *not* an acceptable arrangement.
Here's why this is not acceptable: The equations with
absolute value bars describe relationships that are
wildly different from the real Ohm's law, as illustrated
here: http://www.av8n.com/physics/ohms-law.htm
Believe it or not, I've seen absolute value bars used in
this way.
