The substances which have free electrons(which move freely ) act as conductor while those whose electrons held tightly (which can not move freely) are insulator.

Is a t shirt a conductor or insulator?
A dry T-shirt and most other clothing has air between the threads and acts as an insulator for cold (and electricity). When wet it loses its insulating properties and conducts heat so it no longer keeps body heat inside the clothing. Since perspiration also has salt secreted through the skin, it is also can act as an electrical conductor.
Is slate a insulater?
Yes, slate can be an insulator. Since slate is chiefly carbon based, and many forms of carbon act as a mild insulator, slate could have this property as well. Unfortunately, slate can also contain contaminants that might act as a conductor.
If your skin is moist or wet will it act as a good or poor conductor?
good conductor
What will happen if you nearly touch charged insulator?
An insulator does not generally hold a charge, in fact they resist the flow of electrons, this is what makes them insulators. In some cases though, you can build an electrical charge by rubbing a material (usually fibrous like carpet, wool or hair) with an insulator, though not all insulating materials under all conditions. Mostly this works in cold dry conditions because the air itself will act as an insulator not allowing the static electricity to dissipate through the atmosphere. This is why you get shocked in the winter more than in the summer when you grab a doorknob. As for the charge now accumulated on the insulator, think rubber balloon rubbed on hair, It will tend to stay there until it finds a path to ground. Then the charge will dissipated from the area surrounding the contact, but the areas further away may not dissipated because the electrons can not move across the insulator. To sum it up, the electrical charge will transfer to the conductor but an insulator will not charge under normal circumstances.
Why is gold a good conductor?
Gold, like any other metal, has a "sea" of delocalized/free electrons. These electrons act as "current carriers".
Is a toothpick a conductor or a insulator?
If the toothpick is made of wood or plastic, it would act as an insulator.
Why does a copper wire act as an insulator?
It doesn't, it is a conductor of heat and electricity.
What is a material that has resistance in between a conductor and an insulator?
A semiconductor (like Silicon) can be doped to act like various one way resistive conductors and insulators.
Would a copper wire act as the best insulator of electric current?
no it is good conductor because it has free electrons

What is guard ring?
A guard ring is a circular conductor located near the bottom of a high-voltage insulator string, from where the line conductor or conductors are suspended. It's function is to evenly-distribute the potential gradient across the length of the insulator string, by preventing the concentration of electric field in the vicinity of the line conductor, which would otherwise act to break down the insulating properties of the insulator chain.
Is slate a insulater?
Yes, slate can be an insulator. Since slate is chiefly carbon based, and many forms of carbon act as a mild insulator, slate could have this property as well. Unfortunately, slate can also contain contaminants that might act as a conductor.
Is a basket a insoulator?
Yes, a basket can act as an insulator as it can create a barrier between objects and help prevent the transfer of heat or electricity. The material and design of the basket will determine its effectiveness as an insulator.
Why diode act as an insulator?
Diode is a semiconductor material. so it act as insulator also.
What a insulator?
An insulator is something that keeps heat in, for example, if you put a piece of fake fur around a mug of Hot Chocolate, it would act as an insulator, and would keep the heat in the mug. x if u eant insulator..then it means a poor heat conducto, or poor conductor of electricity ----------------------------------------------------------------------------------------------------------------------------------------------------- Materials that do not easily give up or take on electrons are called insulators.
Can you give me a definition of electrical conductive?
'Conductive', in the electrical sense, describes the property of a material which enables an electric current to pass through that material. An electric current is a drift of charge carriers -in the case of a metal, these charge carriers are negatively-charged free electrons, but in other materials, such as electrolytes (conducting fluids) the charge carriers may be charged atoms, called ions. For a material to act as a conductor, it needs to have sufficient charge carriers to support current flow; if there are too few, then we say the material is an insulator. There is no such thing as a 'perfect' conductor or a 'perfect' insulator, but we can list different materials on a scale where one end represents an excellent conductor (or a very poor insulator) and the opposite end represents an excellent insulator (or a very poor conductor). The property used to define whether a particular material is classified as a conductor or an insulator is termed its 'resistivity', expressed in ohm metres.
