What does a insulator and a conductor mean?

Answer 1

An insulator is a material that prevents the passage of electricity. An example is the plastic insulating cover on electrical wires,

A conductor is a material that allows electricity to flow. An example is the copper wire used inside electrical cables.

Answer 2

An insulator, also called a dielectric ,

is a material that resists the flow of

electric charge . In insulating materials

valence electrons are tightly bonded

to their atoms. These materials are

used in electrical equipment as

insulators or insulation . Their

function is to support or separate

electrical conductors without allowing

current through themselves. The

term also refers to insulating

supports that attach electric power

transmission wires to utility poles or

pylons .

Some materials such as glass , paper

or Teflon are very good electrical

insulators .

conduction

Electrical conduction is the

movement of electrically charged

particles through a transmission

medium ( electrical conductor) . The

movement of charge constitutes an

electric current . This charge transport

may reflect a potential difference due

to an electric field, or a concentration

gradient in carrier density . The latter

reflects diffusion of the charge

carriers. The physical parameters

governing this transport depend

upon the material.

Answer 3

An insulator restrictes electrical flow and a conductor allowes it.
