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 ...

Over the millennia, the phenomenon known as electricity has meant different things to different people. In ancient societies, electricity—or more specifically lightning—was inspiration for some of the ...

Most polymers -- materials made of long, chain-like molecules -- are very good insulators for both heat and electricity. But scientists have now found a way to transform the most widely used polymer, ...

BUFFALO, N.Y. — Looking only at their subatomic particles, most materials can be placed into one of two categories. Metals — like copper and iron — have free-flowing electrons that allow them to ...

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, ...

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 ...

Over the years, Hendrix has maintained that porcelain insulators (and porcelain spacers) should not be used with covered conductor. This is due to the dielectric incompatibility between the two ...

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 ...
