In fact, the speed is so slow that electrons in an AC circuit hardly move at all since they just pace back and forth a very small amount on each half cycle.

No current should flow in this circuit, you’d think, because the pieces of foil can’t touch each other–and without contact, there’s nothing but an insulator to flow across, and electricity doesn’t ...

A river erodes its course. In an electric circuit, does the wiring get eroded by the current, atoms, electrons etc? — Bill "It's a reasonable analogy to think of an electric current acting like ...

In their simulations of 2D semiconductors with strong electron-phonon interactions, the researchers found that when treating both the charge and heat carriers as part of the same system, the ...

However, electric currents in solids are formed by electrons. In metals, the electrons do not collide with each other, but they scatter with lattice defects. In conventional materials, the ...

Physicists report new insights into the behavior of electrons on the surface of a topological insulator, a class of material with unique properties that challenge some of the oldest laws of physics.
