Hi Walt,

R is by definition a physical "property of conductors which depends
on dimensions, material, and temperature". So if we multiply both
sides of our "ratio" equation by I^2 to convert to power we get V*I =
I^2*R. Given that V, I, and R are all non-zero, why would you ask
us to believe that I^2*R and V*I could be zero? It's true that V^2/R
is a ratio. And I guess it's probably also true that the equation
itself doesn't dissipate power. But what would you have us believe
that that is supposed to prove?

I always believed that a ratio was a comparative measure between like
units - e.g. forward voltage to reverse voltage, output power to input
power etc. Voltage to current is not a ratio. V/I has dimensions of
resistance - ratios are dimensionless.
