All* materials conduct electricity. The question is exactly how much do they conduct. Materials such as metals, semiconductors, graphites, etc tend to conduct electricity better than others like plastic, paper, wood, etc due to loose valence electrons that allow electric current to flow through them. Good conductors will have a low electrical resistivity. The resistivity of some common resources are shown:
Gold: 22 n Ω·m
Copper: 17 n Ω·m
Aluminium: 28 n Ω·m
Silicon: 1000 Ω·m
Quartz: 10^16 Ω·m
Rubber: 10^13 Ω·m
Note *: In 2008 scientists discovered a property called a superinsulation that in some materials at a very low temperature exhibit infinitely high resistance. Superinsulation is essentially the exact opposite of superconduction. It's mechanism is not very well understood and is an active area of research in condensed matter physics.

Is wood a conductor or an insulator of electricity?
Wood is an insulator.
Is plastic wrapped around the electric wires is a good conductor?
Plastic wrapped around the wire is insulator. Not a conductor. That is why it is wrapped around the conductor wire.
Is cotton wool a conductor of electricity or an insulator?
Cotton wool is not a conductor or an insulator it is a semi conductor. It is sort of in the middle, electrons can travel through cotton wool but not as good as silver, bronze, metal and so on.
Does bakelite is a poorest insulator?
The poorest insulator would be the best conductor, which is one of the noble metals. Bakelite is a fairly good insulator, not too long ago electrical fittings were made from it.
Explain why the outside cases of electric appliances ususally are made of plastic?
Plastic is a good insulator and a bad conductor of electricity, which makes it a good material to protect people from electric shocks when handling appliances. On top of that, plastics are inexpensive and easy to shape.
Which material is a electrical insulator but a good conductor of heat?
bakelite
When you insulate something you wrap it securely with a material that's not a good conductor or insulator of heat?
insulator
Is a scarf a conductor or insulator?
It really depends what material it is made of, but clothing is usually a fairly good insulator, unless it gets wet.
Is a fork a conductir or insulator?
If it is made of metal, it is a conductor. If it is wooden, it is an insulator.
The difference between a good conductor and a good insulator?
A good insulator means a bad conductor. It is the opposite of good conductor.
Is steel a good conductor or insulator?
Steel is a conductor and not an insulator.
What material has resistance between a conductor and a insulator?
The resistance between a conductor and an insulator is: Wood, fabric, and water!
A conductor differs from an insulator in that a conductor is an?
A conductor is a material that has one or a few electrons in the outer shell of its atoms. These electrons are easily knocked loose, or are already moving about in the material. When a voltage is applied to a conductor, these electrons are repelled by the negative polarity and attracted by the positive polarity. Their movement is called "current". a conductor is a material that transports electrons and electricity can pass through it, metals are good conductors. a insulator is something that is a barrier to electrons and can not pass electricity, rubber is a good insulator.
Material that is a poor conductor?
That is called an insulator.
Is spoon a conductor or an insulator?
it depends on material
What is a material that is a conductor and a insulator?
metaliods trust me
Is a material that is a poor conductor a poor insulator?
No.
