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 ...

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 ...

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 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 ...

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 ...

Long known as the hardest of all natural materials, diamonds are also exceptional thermal conductors and electrical insulators. Now, researchers have discovered a way to tweak tiny needles of diamond ...

Ancient Greeks discovered that when animal fur and amber were rubbed together, the fur could be used to attract feathers, glass dust and other lightweight objects. It wasn’t until 1600 AD, however, ...

ELECTRICITY powers every part of our lives today – from lighting and heating our homes, to keeping public transport systems running. It’s hard to imagine life before electricity – so where did it all ...
