This text discusses the general theory of the electromagnetic field. It presents the expressions for the electrostatic potential and the electric field strength, and it describes how to calculate the potential difference between two points.
Summary
The electrostatic potential is a scalar function that describes the electric field around a point charge. The electric field strength is a vector field that describes the direction and magnitude of the force that a charged particle would experience at a given point. The potential difference between two points is the work done in moving a unit charge from one point to the other.
