In the first fraction of a second electrons flowing through a material (i.e. electricity), they move unimpeded. By "holes" in a resisting material almost immediately begin to resist the flow.
Researchers have captured the onset of electrical resistance.
In this animation of their computational work, the electrons (blue) and atomic nuclei missing an electron -- also called "holes" (because electrons "drop" into them -- (red) show how electrical flow (green) is impeded.
