Has anyone else run into the Pedagogical Position which requires
Ohm's Law to be written with a MINUS sign?!?!?!?!
The justification seems to parallel the addition of the minus sign
known as Lens' Law in the EMF = - d(phi)/dt equation.
I need to be convinced, one way or the other. If it is as 'arbitrary'
as the Lens' Law sign, I'm inclined to leave it OUT!!!
