I recently started a module on heat transfer at my university. and pretty much the first thing we learned was fouriers law.
so for one dimensional heat conduction
q = kA dt/dx
where the heat transfer rate is proportional to the area and the temperature difference but inversely proportional to the thickness of the material.
And this got me thinking, if we consider the temperature difference to be a potential difference and the rate of heat transfer to be a current, we can view the term kA/dx as a resistance term.
I = V/R
and then i thought, that this form of an equation probably occurs in many areas of science.
Does anyone know of a similar example in another aspect of science.?
