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.
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
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.
Materials that have free electrons are good conductors of heat as well as electricity, so they are not insulators
if they are good conductors of heat it means that they are good at transferring heat. an insulator is suppose 2 do the opposite
No - whether you are talking about heat or about electricity, conductor is precisely the opposite of insulator.
That is because conductor means precisely the opposite of insulator.
false because i said!
True..Materials, such as copper or aluminum, that offer low resistance to the flow of electric charge are called conductors.
Conductors, most metals for example, valence electrons of the atoms can be localized with very little input of energy. Insulators, most non-metals for example on the other hand, offers high resistance to flow electrons through them. In insulators valence electrons of the atoms are tightly bound and therefore at low voltages there is no flow of electrons through them.
true :p
A good insulator material is rubber and can block heat and electricity from almost anything. Glass is a good insulator too if you are trying to insulate electricity. Plastic is good as well. Most metals are OK conductors. Copper is very good, and Gold is the best, but it is heavy and expensive.
True if they are conductors, false if they're (or one of them) is an insulator.
True
Leather, wood, and water are examples of insulators, so this is true.

Conductors emerging from the ground must be enclosed in approved raceways. This is to protect the conductors from becoming damaged and starting a fire.
True. Metals are good conductors of electricity because they have a high density of free electrons that can move easily in response to an electric field, allowing the flow of electric current.
false. it does not have to have materials from rock :)
False.
true :p
It is a true statement.
True
true, they did
