#) Relation Between Electric Field & Potential:
+> Electric potential and field are related in that potential is a property of the field that describes the field’s action.
+> The relationship between electric potential and field is similar to that between gravitational potential and field in that the potential is a property of the field describing the action of the field upon an object
+> The electric field is like any other vector field—it exerts a force based on a stimulus, and has units of force times inverse stimulus.e.
+> In the case of an electric field the stimulus is charge, and thus the units are NC-1. In other words, the electric field is a measure of force per unit charge.
