Why is it important to know which materials are electrical conductors and which are electrical insulators?

We need electricity to be conducted in some cases and insulated in others. For example, wires are made of copper due to its low resistance of electricity, allowing less energy to be used but at the same time passed to an appliance. Wire coverings are made of plastics or rubber to protect us from getting a shock when we touch it even when electricity is conducted in the wire.

What does an electrical insulator have?
Electrical insulators are made from materials that are poor conductors of electricity. Metallic elements are good conductors, non metallic elements are poor conductors. Some materials used as insulators are, paper, glass, ceramics, rubber and plastics.
What is the name of materials that are not good conductors of electricity?
They are called insulators. Rubber is an example of a good electrical insulator.More:PlasticGlassAirWoodCeramicPorcelainPaperVarnishMineral OilSlateMarblePolyethyleneSiliconePVCKaptonTeflon
What can not carry electric current easily?
Electrical insulators. Materials such as rubber, plastic, wood, air and some ceramics are all poor conductors of electricity, or good insulators.
What is the definition insulators?
Insulators are materials that prevent electrical flow.
Materials that are not good conductors or and not good insulators are called?
Semiconductor

What a good insulators?
Insulator is a material that resists the flow of electric current. materials such as glass, paper or Teflon are very good electrical insulators. These materials are used to support or separate electrical conductors without passing current through themselves.
What are conductors and insulators of electricity?
Conductors are materials that pass electrical current easily, that is, with low resistance. Insulators are materials that do not pass electrical current easily, that is, they have high resistance. Conductors are ordinarily metals, and insulators are ordinarily nonmetals. Some examples of conductors are: Silver, Copper, Carbon, and Aluminum. Some examples of insulators are Glass, Nylon, and Wood (as well as Air and Vacuum). Conductivity is a function of the mobility of Electrons in the materials in question. Conductors have high mobility and conductors have low mobility. Semiconductors are materials that have some properties of both conductors and insulators. Germanium and Silicon are well known semiconductors. Superconductors are materials that pass electrical current with zero resistance. All known superconductors perform this function only at very low temperatures, far below those encountered in Earth environments (i.e. from around 77 degrees above absolute zero down, or, in other words, below about -320 degrees F).
What carries electric current not easily?
Electrical insulators. Materials such as rubber, plastic, wood, air and some ceramics are all poor conductors of electricity, or good insulators.
What can not carry electric current easily?
Electrical insulators. Materials such as rubber, plastic, wood, air and some ceramics are all poor conductors of electricity, or good insulators.
What are materials that are poor conductors of electricity called?
They are insulators.
Materials that are poor conductors are what?
normally called insulators
What is the definition insulators?
Insulators are materials that prevent electrical flow.
What is the correct name for materials that aren't conductors of electricity?
insulators
Materials that are not good conductors or and not good insulators are called?
Semiconductor
