Fundamentals of Electrostatics: Laws and Fields

Electrostatic:
He studied electrical phenomena caused by static charge distributions, ie the electrostatic field of a charged body.

Gauss's law
Gauss's law says that the net electric flux c, through any Gaussian surface is equal to the net charge enclosed within the surface divided by "0:
Using Gauss's law, one can calculate the electric field due to several symmetric charge distributions.
Typical electric fields calculated using Gauss's law
Insulating sphere of radius R, uniform density and total charge Q
With r> R
With r <R
Thin spherical shell of radius R and total charge Q
With r> R
With r <R
Load lines of infinite length and charge per unit length
Outside the load line
Nonconducting infinite plane loaded with load per unit area
At any point outside the plane
Charged with conducting surface load per unit area
Just outside the conductor
Inside the driver

Coulomb's law is as follows:
The magnitude of each of the electrical forces that interact with two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them in mathematical terms, the magnitude F of the force that each of the two q1yq2 point loads exerted on the other separated by a distance r is expressed as:
F = K (| q1 | | q2 |) / r ²
Coulomb constant
The constant k is Coulomb's constant and its value is 1 / (4 * PI * e )----- The constant ke is the Coulomb constant and its value is9 * 10 ^ (9).

Region of space where they reveal electrical phenomena. It is represented by E and is of a vector (see Vector). In the International System of units the electric field is measured in newtons / coulomb (N / C).
The region of space located in the vicinity of a charged body has special properties. If placed at any point in that region an electrical load test shows that it is subject to the action of a force. This fact is expressed by saying that the charged body has created an electric field. The electric field strength at a point is defined as the force acting on the cargo unit situated therein. If E is the field strength, a charge Q act on a force
F = Q • E
The direction of electric field at any point is given by the force acting on a unit positive charge placed at that point.
The lines of force in an electric field are drawn so they are, in all points, tangent to the field direction, and its positive direction is considered starting from the positive charges on the negative end.
The intensity of an electric field created by various loads is obtained by adding vectorially the intensities of the fields created by each load individually.
