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 ...

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 ...

A new type of switch sends electrons propagating in opposite directions along the same paths – without ever colliding with each other. The switch works by controlling the presence of so-called ...
