Electrostatics

physical property that quantifies an object's interaction with electric fields

The electric field of the charged fur causes polarization of the molecules of the foam due to electrostatic induction, resulting in a slight attraction of the light plastic pieces to the fur. This effect is also the cause of static cling in clothes.]]

a physical law that states the electric force between two point charges is proportional to the product of the charges and inversely proportional to the square of the distance between them.

thumb|Gilbert's versorium The electroscope is an early scientific instrument used to detect the presence of electric charge on a body. It detects this by the movement of a test charge due to the Coulomb electrostatic force on it. The amount of charge on an object is proportional to its voltage. The accumulation of enough charge to detect with an electroscope requires hundreds or thousands of volts, so electroscopes are used with high voltage sources such as static electricity and electrostatic machines. An electroscope can only give a rough indication of the quantity of charge; an instrument t

An electret (formed as a portmanteau of electr- from "electricity" and -et from "magnet") is a dielectric material that has a quasi-permanent electrical polarisation. An electret has internal and external electric fields, and is the electrostatic equivalent of a permanent magnet.

Electrical elastance is the reciprocal of capacitance. The SI unit of elastance is the inverse farad (F−1). The concept is not widely used by electrical and electronic engineers, as the value of capacitors is typically specified in units of capacitance rather than inverse capacitance. However, elastance is used in theoretical work in network analysis and has some niche applications, particularly at microwave frequencies.

Hygroelectricity is a type of static electricity that forms on water droplets and can be transferred from droplets to small dust particles. The phenomenon is common in the Earth's atmosphere but has also been observed in the steam escaping from boilers (see Armstrong effect). It was the basis for a proposal by Nikola Tesla to tap electricity from the air, an idea which has been recently revived. Hygroelectric charge is the likely source of the electric charge which, under certain conditions such as exist in thunderstorms, volcanic eruptions and some dust storms, gives rise to lightning.
