Free teacher resources for Primary Science. Mwaksy Mudenda and Greg Foot create circuits using spoons and dough, to learn about conductors and insulators, why they’re useful and how they keep us ...

Electrical current flows easily through a conductor, but does not flow through an insulator. Find out more with BBC Bitesize. For students between the ages of 11 and 14.

Conductors have a band gap close to 0 eV (electronvolts), semiconductors range approximately between 1 and 9 eV, and anything above is usually considered an insulator.

In some cases, it takes only a single oscillation of light to disrupt the electronic order of a material and turn an insulator into a metal-like conductor.

With this breakthrough, a single material could, in theory, act as both conductor and insulator—simplifying device architectures and unlocking speeds that silicon can’t reach.

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 ...

In general, system construction requires cables to be supported. In our case, the supporting devices for the covered conductor are spacers and insulators. When a polyethylene covered cable comes in ...

Researchers have discovered a material that can switch between an insulator and a conductor freely, even at room temperature. The material, a compound of manganese and sulfide (MnS2), starts off ...

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 ...
