Capacitance is defined as

For a parallel plate capacitor and a dielectric of dielectric constant K, when a dielectric material is inserted between the plates while charge is ______ , the potential difference between the plates decreases by a factor K.

The dielectric constant K of an insulator can be

The dielectric constant K of an insulator cannot be

If the dielectric constant and dielectric strength be denoted by K and X respectively, then a material suitable for use as a dielectric in a capacitor must have

If one penetrates a uniformly charged solid metallic sphere, the electric field strength E
