Edit: Also, another problem I noticed was that even if we remove the negative plate from the capacitor and then apply Gauss''s Law in the same manner, the field still comes out to be $sigma/epsilon_0$ which is clearly wrong since the negative plate contributes to the field. So, maybe the problem is in the application of Gauss''s Law.

Capacitor in Electronics

A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.

Electric field in a parallel plate capacitor

The electric field obeys the superposition principle; its value at any point of space is the sum of the electric fields in this point. Therefore, the field on the outside of the two plates is zero and it is twice the field produced individually by each plate between them. Therefore the magnitude of the electric field inside the capacitor is:
