30-second summary
Electrostatics
Electrostatics is a part of physics that studies electrical phenomena that are related to the steady (time independent) interaction of electrically charged particles and bodies.
The basic law of electrostatics is Coulomb’s law (the First Law of Electrostatics), from which other laws and theorems of electrostatics can be derived.
Many practical applications of electrostatics exist, including photocopiers, laser printers, ink-jet printers, and electrostatic air filters.
About Electrostatics
Electrostatics is a part of physics that studies electrical phenomena that are related to the steady (time independent) interaction of electrically charged particles and bodies. In a broader sense, electrostatics also includes the phenomena of electrification of bodies and (even non-static) manifestations of so-called static electricity.
The basic concept of electrostatics is a static electric field, which can be described by a vector field of electric field intensity or by a scalar potential. The mathematical methods of electrostatics make it possible to calculate the distributions of the electric field and of the electric potential from a known configuration of charges, conductors, and insulators.
The basic law of electrostatics is Coulomb’s law (the Second Law of Electrostatics), from which other laws and theorems of electrostatics can be derived.
