Without more context, it is not possible to determine which point, A or B, has the higher electric potential. Electric potential is a measure of the electric potential energy per unit charge at a particular location. It is related to the electric field strength and the distance from the source of the field. The unit of electric potential is the volt (V).
In an electrical circuit, a voltage difference (or potential difference) exists between two points. This voltage difference creates an electric field, which drives the flow of electric charges (such as electrons) through the circuit. The direction of the electric field is from high voltage to low voltage, and the direction of the current is the opposite of the direction of the electric field.
In order to determine which point, A or B, has the higher electric potential, it is necessary to know the location and strength of the electric field sources, as well as the distance and orientation of the two points relative to the sources. Without this information, it is not possible to determine the electric potential at either point.
