Aren't they both caused by electron motion?
I know two different equations that provides the joule heating effect. The first one only depends on the potential ($\varphi$) and the electrical conductivity ($\gamma$) and can de modeled based on ...
Does anyone know of any materials whereby the thermal conductivity can be changed by passing an electrical current through the material?
I would like to perform an experiment to measure the conductivity of a copper rod. What device can I use to perform to experiment? is there such a thing as a conductivity meter? All i found was an ...
