7.0 Electric field lines
An electric field line is an imaginary line or curve drawn through a region of space so that its tangent at any point is in the direction of the electric field vector at that point.
In other words, it is a way of pictorially mapping the electric field around a configuration of charges.
The relative closeness of the lines at some place give an idea about the intensity of electric field at that point.
