elektrostat
Elektrostat, or electrostatics, is the branch of physics that studies electric charges at rest and the electric fields and potentials they create. It deals with how stationary charges exert forces, store energy, and influence surrounding media, as well as how materials respond to electric fields. In electrostatics, changing magnetic fields are neglected, and Maxwell's equations reduce to a static form.
Coulomb's law gives the force between two point charges: F = k q1 q2 / r^2, with k =
In materials, the field is reduced by the dielectric constant κ, and the permittivity is ε = κ ε0. Capacitance
Charging methods include triboelectric charging (friction), conduction (contact with a charged body), and induction (rearranging charges
The study of electrostatics underpins safety considerations for static discharge and informs the design of sensors,
