    Potential is the voltage . Different locations in a circuit will have different voltages. So there is a potential difference between the 2 ends of a component.

    You know that negative charges are attracted toward a positively charged area and repeled from a negatively charged area. The driving of charges in a circuit is thru a combination of repulsion from one area and towards another area.

    In this context, "drive" means "to propel or carry along by force in a specified direction"
