ELECROSTATIC

It is a branch of electromagnetism

Electrification

Chafe

Induction

Surface charge density

Relationship between the amount of charge present on the body and its external surface

σ=Q\S

Conductors

The charges have greater freedom of movement

Insulators

Insulation polarization

The charges have less freedom of movement

Electroscope

An instrument to identify if it is a body is electrified

Coulomb's Law

F=-K Q1 Q2/R2

ELECTRIC FIELD GENERATED BY A PUNTIFORM CHARGE

ELECTRIC FIELD GENERATED BY A PUNTIFORM CHARGE

Electric potential energy

U=K Q q/R

Electrical potential

V=K Q/R

Two point-like electric charges attract or repel each other with a force inversely proportional to the square of the distance between the charges and directly proportional to the product between the charges

Capacitors

Electric capacity

The constant relationship between the charge present on it and the electric potential that it assumes

Devices whose purpose is to accumulate electric charges

Capacitors in series

Capacitors in parallel
