If you're going to learn about electrical safety for kids, you
should know the dangers of damaged or faulty electrical cords. Have you
ever wondered why appliances have cords with a rubbery coating?
The rubber coating is actually an insulating layer that keeps the electricity trapped inside. An insulator is like the opposite of a conductor. A conductor lets electricity travel through it, whereas an insulator doesn't.
An appliance cord has both a conductor and an insulator. The conductor is on the inside, letting electricity from your wall socket reach the appliance. The insulator is on the outside, trapping the electricity within the cord and protecting you from electrical shocks.
