The educational resource shows a visual about the relation between field intensity and potential: the work carried out by the field when a charged particle moves from one point to another, only depends on the potential at these two points and not the distance covered.

The educational resource shows a visual about the graphically represent the electric field: we use the concept of lines of force.

The educational resource shows a visual about the intensity of the electric field: a body's electric charge alters the space which surrounds it. The magnitude which measures this alteration at a determined point is the intensity of the electric field at this point.

The educational resource shows a visual about the potential electric energy of a charge at a point in the electric field: It is the work carried out by the field when the charge is brought from infinity to the aforementioned point.
