COULOMB'S LAW
Coulomb's Law is a method to determine the electric field intensity and other related parameters for electrostatic charge. It is a universal method, suitable for most condition of charge systems. However, this method is rather complicated for volume charge system. Therefore, we do not cover volume charge using Coulomb's Law.

GAUSS'S LAW
Gauss's Law is a method to determine the electric field intensity and other related parameters for electrostatic charge in simpler way compared with Coulomb's law. However, this method only suitable for symmetrical field. Symmetrical field are contributed by point charge, infinite line charge, infinite surface charge, and also infinite volume charge.

ELECTRIC POTENTIAL
In the existence of electric field, if a charge system is moved from one point to another point, the work done in moving a unit of charge from point B to point A is what we call as electric potential. The aim of this topic are:
-Understand the concept of potential difference and absolute potential
-Calculate potential/potential difference induced by point charges and continuous charge distribution.

ELECTROSTATIC FIELD IN MATERIALS
So far, the analysis of electric field only involve free space / vacuum. When interact with different material, the behavior of electric field will change. we will discuss the behavior of electric field when going inside conductors and dielectric materials.

LAPLACE'S AND POISSON'S EQUATION
Electric potential and Electric field intensity can be determined using Laplace or Poisson equation depend on the boundary condition. Laplacian equation for specific coordinate system can be used to determine the general expression of electric potential and other parameters needed. The knowledge from previous chapter are needed in this chapter.
