Chapter 4 discusses about the concept of potential. There are three different potential that we will cover in this Chapter. Before that; we need to learn what is actually Potential / Electrical potential (Also known as Voltage) and how can we define and derive the potential?

In Part 1, we will discuss about energy. Then later on, you will see in other part that the energy can be used to derive the potential.

In Part 2, we will discuss about electric potential. You will see how we can find the electric potential between two points of interest. The analysis of electric potential can be in cartesian coordinate, cylindrical coordinate or spherical coordinate depend on the situation.

In Part 3, we will discuss one example about electric potential. You will see how we can find the electric potential between two points of interest. The analysis of electric potential can be in cartesian coordinate, cylindrical coordinate or spherical coordinate depend on the situation. This example shows the analysis in spherical coordinate.

In Part 4, we will discuss about Absolute potential. Absolute potential is basically a potential at certain point which its reference is at infinity. However, the reference point can also be somewhere else with given reference voltage.

In Part 5, you will see how to find absolute potential or potential different due to line charges and surface charges. Cylindrical coordinate and spherical coordinate are selected for the analysis.

In Part 6, you will see the relationship between electric potential and electric field intensity using potential gradient.

In Part 7 (Last Part), you will learn how to determine the energy in a Charge systems. The methods to determine the charge system depend on the charge behavior and the coordinate systems.
