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.

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

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 ...

Semiconductors are at the heart of most electronics. We explain what semiconductors are, how they work, and just how tiny those transistors can get.

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 ...

The first pole-top insulators were invented to support telegraph lines in the 1840’s. They were made of glass and functioned both as mechanical support of the wire and to insulate it from the wooden ...

By carefully tuning the chemical composition of a particular compound, researchers have created a topological crystalline insulator, whose bulk acts as an insulator but whose surface conducts ...

A new UB-led study helps solve a longstanding physics mystery about the insulator-to-metal transition.

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 ...
