Insulators and Conductors

Jason Phillips and Justin Aliaga


The definition for an insulator is a substance or device that does not readily conduct electricity. Insulators stop electricity from flowing through. For example a good insulator is rubber. If you connect a wire to rubber and another wire from the rubber to a light bulb, it will not light up. Rubber isn't the only insulator. Other insulators are string, plastic, and many more.

The definition for a conductor is "Electrical conductors contain electric charges (usually electrons) that are relatively free to move through the material; a voltage applied across the conductor therefore creates an electric current". Conductors carry on electricity. Copper pipes, pennies, metal, nails, and more.
