Electrostatic
Electrostatic
Electrostatic (/ɪˌlɛktrəʊˈstatɪk/) is a branch of physics that deals with the phenomena and properties of stationary or slow-moving electric charges.
Etymology
The term "electrostatic" is derived from the Greek words "electron" meaning amber, from which the word 'electricity' is derived, and "statikos" meaning able to stand, or stationary.
Definition
Electrostatics is concerned with the electrical forces between charges that are at rest. It involves the build-up of charge on the surface of objects due to contact with other surfaces. These electrostatic charges can be generated by various means, including friction, induction, and conduction.

- Electric Field: A vector field that shows the direction that a positively charged particle will move when placed in the field.
- Coulomb's Law: The principle that the force between two charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
- Electrostatic Induction: The re-distribution of electrical charge in an object, caused by the influence of nearby charges.
- Electrostatic Discharge: The sudden flow of electricity between two electrically charged objects caused by contact, an electrical short, or dielectric breakdown.
