In the context of electric potential, it is conventional to say that a positive electric potential is higher than a negative electric potential.
Electric potential, also known as voltage, is a measure of the electric potential energy per unit charge at a particular point in an electric field. It is defined as the work required to move a unit positive charge from a reference point to a particular point in the field.
In general, the electric potential at a point in an electric field is directly proportional to the magnitude of the electric field at that point. Electric potential is also inversely proportional to the distance from the point to the source of the electric field. Therefore, a point with a higher electric potential is one where the electric field is stronger, or where the distance to the source of the field is smaller.
In most cases, positive electric potentials are associated with points in an electric field where the electric field is directed away from the source of the field. Negative electric potentials, on the other hand, are associated with points where the electric field is directed towards the source of the field. Therefore, it is generally accepted that positive electric potentials are higher than negative electric potentials.
