If the charge relaxation time, 𝜏cτc, is much lower than the hydrodynamic relaxation time, 𝜏hτh, the behavior of a leaky dielectric liquid approaches that of a perfect conductor, and when the opposite is true, i.e., 𝜏c>𝜏hτc>τh, the liquid behaves as an insulator. The...
@Charred - Fiber optic cable can’t be used to conduct electricity. Remember, it’s made of glass and glass is an insulator, not a conductor. What fiber does is it transmits light, and on that light a bunch of transmission data can travel. That’s why it’s used in telecommunications...

The interpretation of a good electrical conductor at 10–15 km depth as a molten layer is irreconcilable with a thick crust, so that alternative explanations have to be sought for this still enigmatic feature. In the second part, results from different branches of seismology, geochemistry, and ...
