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 ...

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 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.

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 ...

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 ...
