Q:

What are some examples of insulators?

A:

Quick Answer

Some examples of insulators are glass, plastic and rubber. Insulators block the flow of electricity through them due to the stability of the electrons surrounding an atom. However, the electrons in some insulators, such as glass, move more freely in extremely high temperatures and can become conductors.

Full Answer

The rubber coating on electrical wires and the air between the wires are both examples of effective insulators. Insulation forces the electricity to flow between the wires to complete a circuit. The opposite of insulators, conductors have electrons that roam freely and easily transfer electrical energy to other electrons. Water is an example of a conductor. Humans, with a body composition that is 60 percent water, are excellent conduits for grounding electricity.
