Judgment the magnitude of the electric field intensity
According to the density of the electric field line. The more dense the electric field lines, the more the electric field intensity, the less the electric field line, the smaller the electric field intensity.
According to the intensity of the field by the density of the potential surface, the intensity of the electric field is large and the intensity of the electric field is small.
