Continuous Charge Distribution

We have so far dealt with discrete charges but a system of charges can be considered as a continuous distribution if the group of charges are located very close together. To find the electric field due to a continuous charge distribution we have to define the following terms.

Linear Charge Density(l)

Let a charge q be uniformly distributed along a length l, then the linear

SI unit of linear charge is C/m.

Surface Charge Density

Suppose a charge q is uniformly distributed over a surface of area A.

Then the surface density s defined as the charge per unit area.

SI unit of s is C/m².
