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 ...

An electric current is a flow of charge, and in a wire this will be a flow of electrons. We need two things for an electric current to flow: The simplest complete circuit is a piece of wire from ...

A study showing how electrons flow around sharp bends, such as those found in integrated circuits, has the potential to improve how these circuits, commonly used in electronic and optoelectronic ...

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 ...

So many electrons flow in a conventional cable that the current appears to be homogeneous. Although it is not possible to distinguish individual electrons, quantum mechanics says they should exist. So ...

Last year, a new field in solid-state physics termed ‘electron hydrodynamics’ generated huge scientific interest. Three different experiments, including one performed by The University of Manchester, ...

I came to engineering by way of the technician route. I learned electronics in a technical school and was taught that current flow was electron flow and all circuit analysis was done that way.

The phenomenon represents a milestone in the emerging field of ‘atomtronics’, which seeks to create a whole new class of devices that use the flow of atoms, rather than electrons, in a circuit.
