No, most metals are electrical conductors. This means that most metals will conduct an electric current in the presence of an electric field.

What two properties of metal makes it suitable for over head cables?
Metalloids and non-metals make it useful for electrical-------------------------------------------------------------------------Metals are used in wiring to transfer the electrical energy around your home and non-metalic materials i.e plastics are used as insulators.
What Types of building materials are conductors and insulators?
electrical
What are materials that electrical current cannot pass through?
Insulators
What type of material allows a charge to move freely through it?
A material through which an electric current flows easily is called an electrical conductor. Many metals, especially silver and copper, are excellent electrical conductors.
Are most metals conductor or insulators?
conductor- metal (especially copper) is a great conductor of electricity. Silver is a great conductor of heat.
Which metal acts as an insulator?
Metals are conductors, not insulators. Both electrical and thermal conductors.
Are metals good insulators of electricity?
No Metal atoms delocalise eachothers electrons. This means the electrons become free to move. So these delocalised electrons carry electrical charge around. This makes metals electrical conductors, the opposite of good insulators of electricity.
Are metals thermal insulators?
omdat je nou eenmaal moet poepen!!
Are non metal more electropositive than a metal?
There are two types of conductors 1- Metals and 2- Electrolytes, the compounds which become ionized in aqueous solution or in molten state are electrolyte so metal is a conductor of electricity but not an electrolyte.
Do non metals contuct heat?
Non metals do not conduct heat. They have high resistance.They are insulators.Non metals do not have a pool of 'free electrons' (as metals do with metallic bonds). Hence they generally are poor conductors of heat. Nonmetals such as Styrofoam are widely used as insulators. Graphite is an exception as it is a good conductor of heat with its free electrons.Most of the non metals does not conductors because the do not have free electrons. But graphite is a good conductor. Most of the non metals are insulators.
What is the definition insulators?
Insulators are materials that prevent electrical flow.
Is metal a good insulator?
In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them. "Conductor" implies that the outer electrons of the atoms are loosely bound and free to move through the material. Most atoms hold on to their electrons tightly and are insulators. In copper, the valence electrons are essentially free and strongly repel each other. Any external influence which moves one of them will cause a repulsion of other electrons which propagates, "domino fashion" through the conductor.Simply stated, most metals are good electrical conductors, most nonmetals are not. Metals are also generally good heat conductors while nonmetals are not.Source: http://hyperphysics.phy-astr.gsu.edu/hbase/electric/conins.html
What do all electrical insulators have in common?
All electrical insulators have a high resistance to current flow.
Are material that don't conduct electrical charges called insulators?

What are some ways rubber and plastic are used as electrical and thermal insulators?
Plastic and rubber are used to cover electrical cords on most commonly used household electrical devices. You can also find rubber covers under the hood of your car that are used as thermal insulators.
