Insert metal sheet into capacitor
The process of introducing a dielectric slab into a capacitor results in the polarization of the charges present. This polarization leads to the creation of an electric field, which opposes the field induced by the source. Consequently, the net electric flux becomes zero, resulting in an increase in the capacitor''s capacitance. - Download [PDF]
Understanding the Insertion of Dielectric Slab in Capacitor
The process of introducing a dielectric slab into a capacitor results in the polarization of the charges present. This polarization leads to the creation of an electric field, which opposes the field induced by the source. Consequently, the net electric flux becomes zero, resulting in an increase in the capacitor''s capacitance.

This polarization acts to reduce the strength of the electric field between the plates for a given capacitor charge, which allows somewhat more charge to be deposited into the capacitor for a given voltage across the capacitor terminals. 3) Any insulator, including air, will "break down" if the electric field across that insulator becomes too ...
