ABSTRACT
Static electricity is the formation, accumulation, and disappearance of an unbalanced electric charge Q. The unbalanced charge is usually formed on the surface of solid or liquid objects, which can be compact or broken up (e.g. dust and haze particles), of low electrical conductivity (dielectrics, semiconductors), and can conduct objects insulated from the ground. Also, the external electric eld induces the electric charge on the surface of conducting object. In the electried object, there is at least a local lack of equilibrium between the number of elementary positive and negative charges.
