Sep 20, 2020 · Here are common examples of electrical and thermal conductors and insulators. How do you tell whether a material is a conductor or an insulator? A material that transmits energy is a conductor, while one that resists energy transfer is an insulator.
A conductor is a material that allows electricity to flow through it. An insulator is a material that electricity cannot flow through. To determine whether an object is a conductor or insulator, you can build a simple circuit with a battery, light bulb, and three pieces of wire. Touch the free ends of the wire to the object you are testing.

CONDUCTORS AND INSULATORS. We define a conductor as a material in which charges are free to move over macroscopic distances—i.e., they can leave their nuclei and move around the material. An insulator is anything else. In an insulator the charge distribution in an atom may change, but the charges do not leave their nuclei.

Are insulators or conductors in a classroom?
Let students explore other objects that are in the classroom to see if they are insulators or conductors. Make sure the students realize that many objects contain both insulators and conductors. For example, a wooden pencil has a rubber eraser (insulator) surrounded by a metal tip (conductor).
