A plastic bottle is an electrical insulator because it does not conduct electricity. It is made of non-metallic materials that do not allow the flow of electrical current through them.
A glass lens is an insulator as it does not conduct electricity. It is a non-metallic material that does not allow the flow of electrical charge through it.
Glass beads are insulators. They do not conduct electricity because they are non-metallic and have a high electrical resistance, which prevents the flow of electrical current through them.
An example is sulfur.
Sulfur is an element that is a yellow non-metallic solid.
A glass bottle is an insulator, meaning it does not conduct electricity easily. Glass is a non-metallic material that has high electrical resistance, making it a poor conductor of electricity.
Paper has of non -conductive or insulator classification when used in electrical terms.
Of aluminium, silver, paper or copper, only (very dry) paper is an insulator - the thicker the better.
It stops the flow of the electrical current.
Dry straw is an insulator.
Metallic solid is the meaning of a certain alloy that was probably originally liquid but was then manufactured to become a solid metallic alloy. But in non nerd details; a metal liquid turned into a solid metal.
Copper is a conductor of electricity, meaning it allows the flow of electrical current, while polystyrene is an insulator, meaning it inhibits the flow of electrical current. Copper is a metal with high electrical conductivity, whereas polystyrene is a non-metallic, synthetic polymer with low electrical conductivity.
