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

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
