We’re surrounded by electrically powered devices these days. From our lights, to our kettles, and of course our phones! Electricity flows through copper or aluminium wire to power or charge all of ...

The components in a home audio/video system are pretty complicated to anyone without a good understanding of electronics; but wire–good, old-fashioned wire–is something we can all understand. It’s ...

Why do we get shocked when we come in contact with electricity? asks reader Sangpal Meshram. Don't touch an electrical outlet with wet hands. Keep hair dryers away from sinks and bathtubs. And never, ...

Why there’s a need to assess current-flow distribution. How an arrangement was made for the measurement using a controlled magnetic field, laser-induced current flow, and a subtle physics-materials ...

Cambridge researchers have identified a material that behaves as both a conductor and an insulator. The material, samarium hexaboride (SmB6), acts like an insulator in certain measurements, but ...

Regular on/off switches rely on fingers and springs to bring bits of wire together or apart. When the wires touch, electrons flow from one to the other, and your computer/nightlight/sock warmer is on.

Smartphones may one day look just as obsolete as flip phones thanks to spintronics, an incipient field of research that uses electrons' spins to transfer electronic signals. Researchers now report a ...

The performance of an object that has been dependent upon whether the object is composed of a conductive or a nonconductive material. Conductors are materials that allow electrons to flow freely from ...
