Static Electricity
Author(s): Gregory L. Vogt, Ed.D.
Static electricity is an electric charge on the surface of an object. When the difference between the charge on the object and the charge on a nearby object becomes great enough, a spark of electric current leaps between them. Learn about static electricity and watch the sparks produced by a Van de Graaff generator. Find out how lightning is created. See how static charges attract and repel.
