Answer:
7.5
Explanation:
The dielectric constant of ceramics is about 7.5.
The dielectric constant of a substance is the ratio of the electric permeability of a substance to the electric permeability of free space.
Dielectric constant gives a good overview about the ability of substance to store charges compared to another.
Most substances have their electric constant and they suggest the ease by which they can store electrical energy. This is very important in developing capacitors.
