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 ...

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 ...

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 ...

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 ...

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 ...

Some materials that are inherently disordered display unusual conductivity, sometimes behaving like insulators and sometimes like conductors. Physicists have now analysed the conductivity in a special ...

Fine tuning: a new theoretical framework for controlling a system’s properties using laser beams has been developed. (Courtesy: iStock/Swillklitch) Laser light could turn a normally insulating ...

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 ...
