Answer:TRUE

Explanation:Electric field lines are represented by a set of lines with arrows On, the set of lines indicate the direction of flow of electric charge and electric currents. The basic rules guiding the diagrammatic representation of electric field lines is that

(1) The direction of the field lines must be everywhere tangent to the field-lines.

(2) The magnitude of the field is equal/proportional to the number of field-lines in every unit area passing through a small surface normal to the lines.
