# Electric Field Lines

These are imaginary lines drawn in such a way that at every point, a line has the direction of the electric field

Electric Flux Lines

These are imaginary lines drawn in such a way that at every point, a line has the direction of the electric flux density vector

# Properties of Electric Field Lines

1. The direction of the electric field vector  at a point is tangential to the field lines.
2. Electric field lines never cross each other; otherwise the field would be pointing in two different directions at the same point.
3. The field lines must begin on positive charges (or at infinity) and must terminate on negative charges (or at infinity). 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.
