Static electricity is a collection of large amounts of electric charge that does not flow, but discharges very quickly. It is generated when objects become electrically charged by gaining or losing electrons. There are two types of electrostatic discharge - gaining a positive charge through induction or becoming neutral. Coulomb's law describes the proportional relationship between the electric force between two charged objects and their charges and distance. Electrical induction involves the transfer of electrons and separation of charge when charged objects are near each other. The electric field is the region around charged objects where electric forces can be detected, and electric potential is a measure of the work required to move electric charge between two points.

2. Static Electricity
Static electricity (elektrostatic) is a collection of
large amounts of electric charge, the static (no
flow), but in case of discharging the charge time
is very short.

5. C. Coulomb law
Charles Augustin de Coulomb was the first to examine the relationship
with the two charge electric force and the distance between them by
using a torsion balance. In that study ultimately concludes Coulumb in a
law called the law of Coulumb:
large repulsion ataugaya attraction between two electrically charged
objects, is directly proportional to the respective electric charge and
inversely proportional to the square of the distance between the two
charged objects.
Mathematically, Coulomb's law can be formulated:
F = gaya coulomb ( N )

F k 2 r = jarak ( m )
r k = ketetapan 9.109
