• Electric field lines always extend from a positively charged object to a negatively charged object, from a positively charged object to infinity, or from infinity to a negatively charged object.
• Electric field lines never cross each other.
• Electric field lines are most dense around objects with the greatest amount of charge.
• At locations where electric field lines meet the surface of an object, the lines are perpendicular to the surface.

 Objects with greater charge create stronger electric fields. By surrounding a highly charged object with more lines, one can communicate the strength of an electric field in the space surrounding a charged object by the line density. This convention is depicted in the diagram below.
