Static electricity is an imbalance of electric charges within or on the surface of a material.
Xerography
Xerography or electrophotography is a dry photocopying technique.
Electric field
An electric field is a vector field that associates to each point in space the Coulomb force that would be experienced per unit of electric charge, by an infinitesimal test charge at that point.
Electric potential
An electric potential (also called the electric field potential or the electrostatic potential) is the amount of electric potential energy that a unitary point electric charge would have if located at any point in space, and is equal to the work done by an external agent in carrying a unit of positive charge from the arbitrarily chosen reference point (usually infinity) to that point without any acceleration.
Gauss's law
In physics, Gauss's law, also known as Gauss's flux theorem, is a law relating the distribution of electric charge to the resulting electric field.
Electret
Electret (formed of elektr- from "electricity" and -et from "magnet") is a dielectric material that has a quasi-permanent electric charge or dipole polarisation.
Method of image charges
The method of image charges (also known as the method of images and method of mirror charges) is a basic problem-solving tool in electrostatics.
Faraday cage
A Faraday cage or Faraday shield is an enclosure used to block electric fields.
Oil drop experiment
The oil drop experiment was performed by Robert A.
Gaussian surface
A Gaussian surface (sometimes abbreviated as g.s.) is a closed surface in three-dimensional space through which the flux of a vector field is calculated; usually the gravitational field, the electric field, or magnetic field.
Electric potential energy
Electric potential energy, or electrostatic potential energy, is a potential energy (measured in joules) that results from conservative Coulomb forces and is associated with the configuration of a particular set of point charges within a defined system.
Electrostatic discharge
Electrostatic discharge (ESD) is the sudden flow of electricity between two electrically charged objects caused by contact, an electrical short, or dielectric breakdown.
Electrostatic generator
An electrostatic generator, or electrostatic machine, is an electromechanical generator that produces static electricity, or electricity at high voltage and low continuous current.
