Homework Statement
Just a quick question. The electrical field is stronger where the voltage is higher right?
Or does it have to do with how close together the equipotential lines are?

"Potential arrow"? The equi-potential lines should have no arrows. They are perpendicular to the field lines. Arrows on a field line point in the direction a positive particle would move.JanClaesen said:Is the direction of a potential arrow the direction in which a positive particle would move?

Equipotentials are imaginary surfaces in an electrical field where the potential (voltage) is the same at every point. In other words, the electric field lines are always perpendicular to equipotential surfaces. This means that no work is required to move a charge along an equipotential surface.
Equipotentials are often represented by contour lines on a two-dimensional map, while electric field lines are drawn as arrows pointing in the direction of the electric field. The closer the equipotential lines or electric field lines are to each other, the stronger the electric field at that point.
Equipotentials are important in electrical systems because they provide a way to understand the behavior of electrical fields. They help us visualize the strength and direction of the electric field, and also aid in calculating the potential difference between two points in the field.
The electric field strength is directly proportional to the distance between the equipotential lines. This means that the closer the equipotential lines are to each other, the stronger the electric field at that point.
No, equipotentials cannot exist without an electric field. In order for there to be an equipotential surface, there must be no change in potential (voltage) along that surface. This can only occur in the absence of an electric field.
