Wire
Storyboard
The geometry referred to as a wire can be understood as an infinitely long cylinder where the distance to the axis is much greater than the radius of the cylinder. Essentially, this corresponds to a case where the radius approaches zero, effectively becoming an infinitely thin line of charge.

Electric field of an infinite wire
Description
Since Gauss's law states that the total flow of electric field through an infinite cylinder is proportional to the enclosed charge, using 11377
:
can be applied to the case of a single surface Surface ($S$) corresponding to a cylinder of Radius ($r$) and Wire length ($L$):
With this you finally obtain:

Linear Charge Density
Description
When Charge ($Q$) is distributed over a Wire length ($L$), a Linear charge density ($\lambda_e$) can be defined that represents the amount of charge contained per unit length:
From this linear load distribution it is defined:
 $\lambda_e = \displaystyle\frac{ Q }{ L }$
