Electric fields point from higher potential to lower 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).
The electric field is a region in which electric charges (such as electrons) are subjected to a force. It is created by a voltage difference (or potential difference) between two points. The direction of the electric field is from high voltage to low voltage, and it points in the direction that a charged particle would need to be moved in order to release some of its electric potential energy.
In an electrical circuit, the electric field drives the flow of electric charges through the circuit. The direction of the current is the opposite of the direction of the electric field, so the current flows from high voltage to low voltage.
