The capacitance of a parallel plate capacitor when the plates are separated by air or free space. A parallel plate capacitor with a dielectric between its plates has a capacitance that is sensitive to the dielectric constant of the material. The maximum electric field strength when an insulating material break down is called dielectric strength.

There is a net separation of positive and negative charges in an isolated polar molecule, whereas there is no charge separation in an isolated nonpolar molecule. In other words, polar molecules have permanent electric-dipole moments and nonpolar molecules do not. Nonpolar molecules can become polar in the presence of an external electrical field, which is called induced polarization.

Without dielectric, the charge on the plates is Q0=C0V0=(20.0pF)(40.0V)=0.8nC. Since the battery is disconnected before the dielectric is inserted, the plate charge is unaffected by the dielectric and remains at 0.8 nC.
