Electrostatics is the branch of physics that studies electric charges at rest and the electric fields and potentials they produce. In practical terms, it deals with forces between stationary charges, the fields those charges generate, and how materials respond to electric fields. The fundamental interaction is described by Coulomb’s law, which states that the force between two point charges q1 and q2 separated by a distance r is F = k q1 q2 / r^2, where k is Coulomb’s constant.

Key concepts include the electric field E, defined as the force per unit charge (E = F/q) and the electric potential V, where the field is the negative gradient of the potential (E = -∇V). Gauss’s law, ∮E·dA = Q_enclosed/ε0, relates the field to the enclosed charge and underpins flux concepts and symmetry analyses. Materials respond to fields through permittivity ε = ε0 εr, with dielectrics reducing the field inside them.

Capacitance C, defined by Q = C V, measures a system’s ability to store electric charge, and the associated energy U = (1/2) C V^2 describes the work required to assemble the charge distribution. Electrostatics also explains shielding effects, such as Faraday cages, and charge redistribution by induction.

Generation and control of static charges follow methods like friction, contact, or induction, but practical work emphasizes preventing unintended discharges. Applications span electrostatic precipitators in pollution control, electrostatic painting and coating, xerography, and various printing technologies.

In Spanish usage, electrostática is the term for the field, while electrostáticamente translates as “electrostatically,” describing processes or effects related to static electric charges.
