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 ...

University of Cambridge researchers have discovered that a material already known for its peculiar electrical properties appears to behave as both a conductor and an insulator at the same time. This ...

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, ...

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 ...

Ohm’s law is well-known from physics class. It states that the resistance of a conductor and the voltage applied to it determine how much current will flow through the conductor. The electrons in the ...

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 ...

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 ...

Semiconductors have a rare ability to act like both conductors and insulators, depending on how they’re used. This video ...

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 ...
