Gauss's law for electrostatics

Gauss's law for electrostatics states that the total electric flux passing through a closed surface is proportional to the total electric charge enclosed within that surface. Essentially, it means that if you imagine drawing an imaginary skin around a charged object, the amount of electric field lines that pass through this "skin" directly relates to how much charge is inside. This principle helps us understand how electric fields behave around charged objects and allows us to calculate electric fields more easily in certain symmetric situations, like spheres or cylinders.
