The key point of this lesson is that "If the number of electric field lines that penetrate a unit area is determined to be E, the total number of electric field lines j is 4π × (Coulomb's constant) × (electric charge of a point charge), and the number of electric field lines that penetrate a closed surface is proportional to the electric charge inside the closed surface (Gauss' Law)."
