Viscosity, resistance, and temperature

AI Thread Summary
Increasing temperature leads to higher electrical resistance in wires, as described by Ohm's Law (I = V/R). In contrast, viscosity, which measures resistance in fluids, typically decreases with rising temperature in liquids, though it increases in gases. The differing behaviors of viscosity and electrical resistance highlight that they are not analogous and are governed by distinct physical principles. The relationship between temperature and these forms of resistance varies significantly based on the state of matter involved. Understanding these differences is crucial for applications in both electrical and fluid dynamics contexts.

When temperature increases, the resistance in a wire also increases. ( I = V/R )

However, when the temperature increases, viscosity (resistance in a fluid) decreases...


These are both resistances. Why does temperature increase cause an opposing effect in them?

Viscosity and electrical resistance are not analogous quantities. Additionally, viscosity increases with temperature in a gas but decreases with temperature in a liquid. It is a completely different physical phenomenon than electrical resistance.
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...

Thread 'Why measure the speed of light in one direction?'

It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
