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.
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.
An insulator restrictes electrical flow and a conductor allowes it.
nether.
The metal part itself would be a conductor in theory but the handle would be an insulator as it is usually rubber or plastic.
Insulator
Glass has a higher conductivity than thin plastic but,it is still lower than metal so metal may be a better conductor
Conductor-one which conducts(allow current)electric city in all condition. Semiconductor-One which behaves like conductor as well as insulator depending on condition. Insulator-one which donot conduct(allow current)electric city in all condition

insulator.
It is an insulator
conductor
insulator
conductor!!!!! ;))
yes
Its a insulator
it is a conductor
i think the tweezer a conductor
