True Or False Materials that are poor conductors are poor insulators?

Answer 1

No. Something that is a poor conductor must be a good insulator and vice versa. If a material conducts better than it insulates it is considered a good conductor, if it insulates better than conducts it is considered a good insulator. No material can be both a poor conductor AND a poor insulator. It is impossible.

Answer 2

If you're asking if good conductors are also poor conductors, then no.

If you're asking for a list of good conductors and poor conductors...

Good: Metal, Steel, Graphite , water

Bad: Rubber, String

Answer 3

An insulator is a material that has insufficient free charge carriers to support electric current. Most practical insulators are compounds, i.e. they are made of of molecules comprising different elements. These include porcelain and glass (used to support transmission/distribution lines), various rubbers and plastics (used to insulate electric cables), various oils (used to insulate transfromers, capacitors, circuit breakers), and gases (used to insulate busbar systems). Dry air is the most common practical insulator, enabling high-voltage overhead lines to operate without additional insulation except where they are supported from towers or poles.

Answer 4

Materials that have free electrons are good conductors of heat as well as electricity, so they are not insulators

Answer 5

if they are good conductors of heat it means that they are good at transferring heat. an insulator is suppose 2 do the opposite

Answer 6

No - whether you are talking about heat or about electricity, conductor is precisely the opposite of insulator.

Answer 7

That is because conductor means precisely the opposite of insulator.

Answer 8

false because i said!
