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.

For example, in so-called Mott insulators, the electrons ought to flow freely and the materials should therefore be able to conduct electricity as well as metals.

Insulators made into conductors: Polymers coaxed to line up, transformed into materials that could dissipate heat Date: March 9, 2010 Source: Massachusetts Institute of Technology Summary: Most ...

When polyethylene insulators are used, there is no dielectric incompatibility, and the voltage is evenly shared along the insulation system.

Basic experiments on the role of several major parameters relating to ice accretion, insulator characteristics and voltage type and polarity, on the maximum withstand voltage of short insulators, are ...

At ETH Zurich researchers have observed a new state of matter: in graphene layers twisted relative to each other, two electrical conductors team up to form an insulator.

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 ...

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 ...
