charge

Overview page. Subjects: Chemistry — Physics.

A property of some elementary particles that gives rise to an interaction between them and consequently to the host of material phenomena described as electrical. Charge occurs in nature in...

Charles Augustin de Coulomb

Overview page. Subjects: Science and Mathematics.

(1736–1806) French physicist,

who served as an army engineer in Martinique before returning to France. He is best known for his 1785 proposal of inverse-square laws to describe the...

Earnshaw's theorem

Overview page. Subjects: Chemistry — Physics.

A fundamental result concerning bodies that interact according to inverse square laws, such as Coulomb's law of electrostatics and Newton's law of gravitation. It states that a system...

electric field

Overview page. Subjects: Physics — Chemistry.

A region in which an electric charge experiences a force usually because of a distribution of other charges. The electric field strength or electric intensity (E) at any point in an...

electrostatics

Overview page. Subjects: Chemistry — Physics.

The study of electric charges at rest, the forces between them (see Coulomb's law), and the electric fields associated with them. Compare electrodynamics.

fundamental interactions

Overview page. Subjects: Physics.

The four different types of interaction that can occur between bodies. These interactions can take place even when the bodies are not in physical contact and together they account for all...

inverse-square law

Overview page. Subjects: Science and Mathematics — Medicine and Health.

The principle according to which the intensity of a wave, including a light wave or a sound wave, decreases in proportion to the square of the distance from its source.

Maxwell's equations

Overview page. Subjects: Physics.

A set of differential equations describing the space and time dependence of the electromagnetic field and forming the basis of classical electrodynamics. They were proposed in 1864 by James...

permittivity

Overview page. Subjects: Physics.

Symbol ε. The ratio of the electric displacement in a medium to the intensity of the electric field producing it. It is important for electrical insulators used as dielectrics.

static electricity

Overview page. Subjects: Physics.
