WHAT IS ELECTRIC FIELD LINES AND ELECTRIC FIELD?

An electric field line is an imaginary line or curve drawn through a region of empty space so that its tangent at any point is in the direction of the electric field vector at that point. The relative closeness of the lines at some place gives an idea about the intensity of electric field at that point.

An electric field is a region around a charged particle or object within which a force would be exerted on other charged particles or objects.
