For the case where the force of the field crosses the surfaces, normally it passes through anyone, considering a uniform electric field, it is evident that it has the same intensity at all the points that are in it, that is why under the scheme of Fadaray, where the electrical phenomena in this context, has the property where a line of the east field is represented tangent, with respect to the vector of force intensity within the electric field, which can be represented with a simple equation: E x dr = 0, where E is the intensity of the field and dr is the distance of the tangent of the vector.
Flow of an electric field: defined as this magnitude helps, in certain cases to calculate the expression of the electrostatic field (at all points in space) created by some charge distributions, helping to solve the fundamental problem that arises in electrostatics .

Something very curious, but interesting within the electric field are particles, which move along a line, where it is simply oriented according to the force exerted within it, in such a way that the lines of the particles that they have positive charges come out within the field, to be able to enter the particles that have negative charges.
The influence is the separation or displacement of electric charges due to defects in an electric field. Information consulted in Electrotechnics by Peter Bastian, 2001.
