How fast electrons move in metals. Compare it to the speed of light.

In between the spatial holes between molecules / atoms / crystal lattices will be equal to the speed of light. In other cases, their speed depends on the type of metal, the density of atoms and the type of crystal lattice, the strength of the current passed through the metal and even the temperature and magnetic field around and will be measured from about 0.6-6 mm / s to 8-10 m / s …
